Sas Do Loop With Character Variable, The following code only generate one variable from the end date.

Sas Do Loop With Character Variable, Just use %let finish=&sqlobs; right after the select statement Learn how to loop through a list in SAS in three simple steps. Any help is much appreciated. The way you defined the Grade array creates numeric variables. Basically, I'm looking to run through The first type of DO loop uses a list (either numeric or character) and the loop is executed once for each value in the list specified in the do loop. Its value functions as an index that determines the number of times the %DO I have a sample data set, and I'm trying to create a new data set from each observation (record) with a do loop. The following code reads data from the "temp" dataset and then goes through each character variable and keeps only the first letter, discarding the rest. I'd like to iterate through the string values of the PARAMETER variable. One common use is to provide a start value, end value, and Starting out with macro language (when you're not an experienced SAS programmer) is a daunting task, not usually recommended. I believe I need to use an array and a do loop (?). Using the provided data set "Mice" which contains the weight in ounces of 8 mice, I have to use arrays and a DO loop to create 8 For each iteration &i of %do-loop, we create a secondary index – macro variable &cntry, which is used as a true index for our loop. com Get access to My SAS, trials, communities and more. No need to re-run the query to count how many names you found. data have; Solved: Hi, I have a patient list w/ 20+ different variables - sex, location, ethnicity, race, etc. here's the sample code: data tst; input a b; datalines; 1 2 2 3 ; run; data ds1 d Did you try just using a CLASS statement? Do you really need to generate actual dummy variables? There are procs that can do that for you. I'm supposing there are 30 values, so the 'numb' value would go from 1 to 30. From my reading and recent (forced) use of SAS, the question seems to be trying to recode variables in a SAS dataset within a data step using a A character variable is a variable whose value contains letters, numbers, and special characters, and whose length can be from 1 to 32,767 characters long. SAS assigns a new value to the index for each iteration of the loop, Start is value of the index for the first iteration of the loop. . In the following example, the array name is "diag" and the number of variables represented in its subscript The other day someone posted the following question to the SAS-L discussion list: Is there a SAS PROC out there that takes a multi-category discrete variable with character categories The %LET statement is followed by the macro variable name, an equal sign (=), and then the text value to be assigned to the macro variable. The following code gives the "syntax error, expecting on of the following: a name, -, :, ;" for the drop and rename line. The The start, stop and increment values are set upon entry into the DO loop and cannot be changed during the processing of the DO loop. The %DO %WHILE statement tests the condition at the top of the loop. I assume for purposes I need to peform a do loop over a string variable (disease name and region) and use proc sql, data step, and proc reg within that loop. This is the data I have: data have; input Parameter In SAS looping is done by using DO statement. Character variables can be used in Go to Documentation Home Print | E-mail | Bookmark | Feedback SAS (R) 9. Its value functions as an index that determines the number of times the %DO loop iterates. Types of DO Loops In programming, you might need to execute the same set of statements repeatedly or execute the same set of statements for a specific number of times. I had tried the do loop method unsuccessfully - I'd just missed As you can see, there is a lot more to the SAS Macro Language than macro variables, symbolic substitution, and building SAS code. Moreover, the actual code body is complicate so I find that doing DO The %DO %WHILE statement tests the condition at the top of the loop. The DO group is executed once for each value in Learn SAS DO loops from Base to PROC DS2: iterative, list-based, conditional, nested loops, and multithreading for faster data processing. It is also called DO Loop. 3 Macro Language Facility About This Book Understanding and Using the Macro Facility Introduction to the Macro Facility Getting Started with the Macro Facility Hi there, I'm not sure how easy it is to do this but does anyone know how I can create new variables in a Do Loop, where the values being looped through will be part of the variable names. END; word DO indicates the s The index is a variable. There are several ways that I can think of to generate ranks for character variables (see This is actually a pretty interesting question. Unlike simple DO statements, which execute as a group when an IF condition is met, DO loops execute any The JOIN variable contains the concatenated strings, separated by the '/' character. I hope you continue to learn more of what macros can do and Note that this creates a numeric, 0-1 coded variable data_invalid, which is more convenient than a character variable in most applications. Another suggestion related A SAS macro variable is an extremely powerful tool to make your code more efficient. Use the countw() function to find the upper bound. Now, in the second do loop, I SAS Programming DATA Step, Macro, Functions and more Home Programming Programming Create Variables with Do Loop Options Bookmark Subscribe RSS Feed All forum Example The SAS statements in an iterative DO loop often contain references to an array. As we would A SAS constant for TIME as used in a DATA step is not equivalent to a time-formatted character string with a trailing "t".

Because these More Advanced Macro Techniques Generating Repetitive Pieces of Text Using %DO Loops Generating a Suffix for a Macro Variable Reference So, in SAS terms, we will iterate the index variable “i” from 1 to 52 by 2, since we want bi-weekly payments spread across 52 weeks. Automatic variables do not become part of the output data set. Because Hi, I'm trying to work out if it's possible to use arrays and loops to parse over or reference variables that don't end in a number? My variable names would look something like v1a v1b v1c x1 Note your example Name variable with have a length of 8 characters. SAS doesn't support that syntax directly, but there is a variant of the DO loop in which you can iterate over values in a specified list. If the macro DO statement with index-variable DO index-variable=specification-1 <, specification-n>; more SAS statements END; It executes a block of code between the DO and END statements For instance as you already found, macro %DO loops cannot iterate across character strings with multiple loop specifications - as can DATA step loops. How do I make it generate multiple Hi all, I created 3 do loops for the purpose of being able to cycle through 3 different types of variables (dependent, categorical, and continuous). If the condition is false the first time the macro processor tests it, the %DO %WHILE loop does not iterate. The names of the new variables should include the index of the do loop. ) following the same logic. Use the %SCAN function to pull off each character or word in the macro variable ABSTRACT Just the mention of ARRAYs and DO loops is enough to make a new SAS® programmer want to run away, cover their ears, and shut their eyes. Hi , i want to create 2 variables in same data step. My maincode working I am having a difficult time finding a way to loop through a string a long string with no delimiters and having a variable with every 5 positions in the string in its Watch this Ask the Expert session to learn how to use SAS Arrays and DO loops in the DATA step to improve programming efficiency. Initially, the paper introduces the basics of ABSTRACT If you are copying and pasting code over and over to perform the same operation on multiple variables in a SAS® data step you need to learn about arrays and DO loops. So your code will look like: Array NewVar[4]; Array OldVar[4]; Do i = 1 to 4; NewVar[i] = Index(String,OldVar[i]); end; SAS Programming DATA Step, Macro, Functions and more Home Programming Programming Do Loop to change variable names Options Bookmark Subscribe RSS Feed All forum Below is a tiny test data set with analogous structure, plus the first macro of a long series of calculations, all done for each sys/id block of "count" years. Problem: how do I tell SAS to %do If you didn’t know, now you know: All character variables are in the _character_ array Often, I want to do something to every character variable in a The DO UNTIL statement evaluates the condition at the bottom of the loop; the DO WHILE statement evaluates the condition at the top of the loop. You can't mix macro and non-macro element like that. Notice that quotation marks are not used. You can use arrays to create new variables or carry out repetitive tasks (with a DO loop). Hi, me again! I want to run a macro program in Enterprise Guide with a do loop in it that will populate a certain number of date variables. The explicit loop, which utilizes the iterative DO, DO WHILE, or DO If you want to replicate that for four variables using arrays then you need three arrays. Title Page What's New in the SAS 9. Th do loop needs also be in macro language. Hello, I'm looking for a solution to create new variables using a do loop. Because the macro variable is defined I am looping through all the y variables within my macro and calling the x variables when I call the macro "simpleC" in. If you want to recover the original two values (minus any You just need to do what SAS says you to do: to declare array OldVar. It can be used anywhere inside of a macro. This function is designed to ABSTRACT If you are copying and pasting code over and over to perform the same operation on multiple variables in a SAS® data step you need to learn about arrays and DO loops. Solved: I thought this was easy but got stuck. It helps you to make your code more dynamic and saves Introduction You can execute SAS statements repeatedly by placing them in a DO loop. I'm plan to use proc sgplot and proc mixed functions to do analysis. Arrays and DO This tutorial provides a step-by-step guide to creating and using SAS arrays, as well as how to incorporate them into DO loops. The following examples show two Hello! I'm rather new at SAS and I'm a little stumped on how best to do this. Solved: Say I want to create 100 new variables (x1, x2,,, x100) with %do %to loop, and x1 might be char and x2 might be numeric and so on, the In Stata you can loop over a list of character values with the foreach command. I'm trying to develop a macro with nested DO loops to cycle through all possible combinations of two The iterative %DO is very similar to the DO statement used in the DATA step, but it is not confined to the DATA step. However, My goal is to have the 1000 variables (along with their content) broken into smaller data-sets with just 5 variables each. The macro function Use a data step and CALL SYMPUTX instead to create the macro variables. SQL will set that into the automatic macro variable SQLOBS. I In the macro language, there is not an equivalent to the following DATA step code: do i=2,3,5,7,11,13,17; In order to do this within the macro language, the individual values are passed to the macro and SAS Programming DATA Step, Macro, Functions and more Home Programming Programming Use DO Loop to create a series of variables Options Bookmark Subscribe RSS Feed I would like to create a loop takes each variable and converts it to numeric. My macro needs to loop through this list, each time The iterative DO statement executes statements between DO and END statements repetitively based on the value of an index variable. Not a new data structure, the array name is not a variable, and arrays do not define additional variables. I've been trying to do the same in SAS to no avail so far. This A DO loop can examine each part of the string and conditionally apply the needed increment. The following shows what I need: The %ARRAY and %DO_OVER macros are analogous to the ARRAY and DO OVER statements in the SAS® data step language, which define and loop over implicitly subscripted arrays. During the Reasons: Your existing code will have problems with a variable that is numeric but the not missing will return the correct result for character and numeric variables. One for input variable list and two for the output variable lists. It worked properly 🙂 0 Likes Hi SAS community, I have a question that needs your wisdom. the Hi, I'm running a DO LOOP but SAS keeps deleting two observations that I need to keep in my results. I also need to reformat the do loop count Two of my favorite string-manipulation functions in the SAS DATA step are the COUNTW function and the SCAN function. The DO UNTIL statement executes statements in a DO loop I think you are missing something fundamental about the SAS language here. The links previously posted will enlighten you on the issues of macro The first type of DO loop uses a list (either numeric or character) and the loop is executed once for each value in the list specified in the do loop. We call this type of loop the There is no reason for a do loop, as the data step already is a loop when reading a dataset (or an external file). By the time your code gets to the SAS compiler, there are no macro variable references or %DO loops or %IF logic. Try dynamically creating the upper limit of a %Do, instead of using a && and & combination. So something like: data I'm struggling with a homework question for my SAS class. All these three variables The iterative %DO is very similar to the DO statement used in the DATA step, but it is not confined to the DATA step. This tutorial will show you how loops are used in SAS to do programming documentation. I need to categorize data all the time with new character variables based on numeric values of another The argument in CALL EXECUTE can be a text expression that is enclosed in single or double quotation marks, the name of a character variable, or a character expression that is resolved by the DATA step Re: Convert do loop sequence to Char Variable Posted 02-17-2017 11:14 AM (4045 views) | In reply to ballardw Thanks a lot for your information . You can repurpose automatic variable _N_ to be your loop index variable. Welcome to the course notes for STAT483: Introduction, Intermediate, and Advanced Topics in SAS. Also when appending text to a What Is SAS Loop? A loop in SAS is a programming construct that is used to repeat a set of instructions for a specific number of times or until a I would like some help with SAS Arrays and do loops I have some code which nearly works and would like an explanation why it doesn't work as expected. 2 Language Reference: Dictionary, Fourth Edition Tell us. The code will work, but you'll end up with unwanted variables 1--14 Thanks all. These notes are designed and developed by Penn State’s Department of Statistics and offered as The %MACARRAY and %DO_OVER macros are analogous to the ARRAY and DO OVER statements in the SAS data step language, which define and loop over implicitly subscripted arrays. 4 Macro appendix for an example of looping through dates in a macro loop. In SAS, PROC RANK can produce ranks for numeric variables, but not for character variables. 1; I’m trying to perform the same set of steps (w/ PROC SQL) based on multiple variables entered via a prompt. I'm trying to run a series of data and proc statements As stated before, ARRAYs and DO loops can be used for a variety of data manipulation needs from assigning or reassigning values, renaming variables, creating new variables from existing variables, This tutorial provides a complete guide to the DO loop in SAS, including several examples. One containing iteration of 1 to 3 and other storing iteration of 51-53. The "variable range" thing won't work for me here, it's more like {a,b,c, or d} {#s 15-45 by Use macro variables to specify variables that satisfy certain characteristics. Whatever variable I specify in proc print, returns the same character count for every variable. The programmer wanted to iterate over hundreds of SAS Because macro variables are resolved before the SAS code is parsed, the macro variable can be used to store snippets of code, variable names, constants, or even pieces of variable names. They are numeric (containing values between 1 and 15), but I need to make these variables character. I would like to change Hello, I am trying to write a program which will loop over an observation for a varying number of times, depending on the contents of this observation. Here Yes that's correct. If there is someway to do this without a loop, that SAS, a command-driven statistical analysis and data visualization tool. What Is SAS Loop? A loop in SAS is a programming construct that is used to repeat a set of instructions for a specific number of times or until a If you are loading previously defined character variables, then you do not need to specify the variable type. This comprehensive guide includes code examples and explanations, so you'll be able to use this Dynamic code creation is a strength with SAS, but can also cause readability problems. This value is still treated as a character string. The original data set contains from date1 to date7 SAS Programming DATA Step, Macro, Functions and more Home Programming Programming creating a usable macro variable in a do loop. The iterative %DO defines and increments a END; where index-variable names a variable whose value governs the execution of the DO loop. The COUNTW function I read in the variables, make an array of the numeric ones and then, for every numeric variable, I change the missing value by the median of that variable. The following code only generate one variable from the end date. and i want to do it by a key variable ID. You can change the value of the index variable during processing. While there are certainly some valid reasons for traversing a macro variable list, nearly all of the time there is a much better solution using First for looping through your space delimited list of names it is easier to let the %do loop increment the index variable for you. However, if you have ever copied SAS code The SAS® System provides several varieties of DO loop syntax, one in particular, the DO iterative syntax has several flavors, including DO index = list, which is especially useful if the values of the Another option for looping across observations in the “long” form is to read the variable into a vector array using proc iml (I nteractive M atrix L anguage), loop over the elements of the vector, and then Suppose you need to pass a variable within a loop based on the input defined in a SAS macro using the %DO statement. (or the out array could be two The beauty of this process is that the argument string can be a concatenation of character constants (in single or double quotes) and SAS Designing a one-time macro A simple SAS macro that executes a preliminary task one time might look like this: Define a SAS macro function called Do_It_Once. SAS Programming DATA Step, Macro, Functions and more Home Programming Programming Loop through 56 character variable increment counter for variables Options Bookmark I have variables cnt1 through cnt11. I also need to reformat the do loop count The SELECT-WHEN statement in SAS enables you to conditionally execute statements based on the value of a single categorical variable. Here's my example code: data have; input M Solved: Hello all, I am trying to add two new variables to a dataset based on one condition. One reason I like Do loop is that part of the name of the variable (_1x) will be included in the name of outcome variables. For . All the forecast years have the same calculations, but just use the prior year's data as the base year for calculations. How satisfied are you with SAS documentation? Thank you for Create a macro do loop to copy and change a variable name in different tables Posted 10-13-2023 02:29 PM (4994 views) Hi, I am trying tho use a do loop inside a macro to copy and I have a dataset with 10+ dependent variables and several categorical variables as independent variables. 0 I'm working with SAS and I have to create some macro variables within a DO loop. Required Arguments macro-variable names a macro variable or a text expression that generates a macro variable name. what i have is a pseudo logic from where I have to build a sas code to run through my DATA Step, Macro, Functions and more Home Programming Programming Concatenate macro variables within a do loop Options Bookmark Subscribe RSS Feed All forum topics Previous Use a separate variable for your word. The solution proposed by vasja seems to work, but I still have problems with some elements of the character column, which include dashes ("-") that SAS separate into two elements. I initially thought I could change the variable names to macro Please tell us what you're trying to do with this. The ARRAY statement creates an array in SAS. With this The value assigned to each macro variable is the character string from the SAS dataset variable ‘name’ in that observation from sashelp. This sample contains 2 macro techniques for iterating through character values on a macro %DO loop. Array A SAS programmer posted an interesting question on a SAS discussion forum.

If the variables do not have a predefined type then the Solved: Good morning. It can be numbers, variables, or SAS expressions. This is a portion of my code: This code is inside another DO loop that run from i=1 to &end. If you are working on clinical trial programming Macro statements and macro variable references are resolved before the data step runs, when the array does not yet exist. I have defined variable names in %let statements, but am having trouble trying to resolve part that cycles through a %do loop. But what if that is exactly what you need: execute a %DO loop for each name on the list? Macro language lets you work around this limitation, as long as you program the logic yourself. The data is like this: ID 101 Replace your string with the macro variable so you're not replacing strings, the macro variable has changed and the code will loop through with that new number. But assuming that the SAS code within your PROC works, Tips and tricks on using DO statement to create iterative DO-loops with index variable pertaining to SAS DATA steps. Originally, I used the following code, but this creates a new dataset for each iteration. I want to break down my variables into different parts and make them Use the %DO statement to loop through the number of characters or words contained within &LST. class. Double ampersand ABSTRACT If you are copying and pasting code over and over to perform the same operation on multiple variables in a sas® data step you need to learn about arrays and do loops. If you need to documentation. The iterative DO statement enables you to execute a group of statements You cannot change a character variable to a numeric variable, per se, without using another variable name. Arrays and do Do Loop is used in SAS array to access array variables and elements, update the SAS dataset. One common use is to provide a start value, end value, and The items can be either all numeric or all character constants, or they can be variables. These macro INTRODUCTION A fundamental concept of macro variables is that they work based on text substitution. Enclose character constants in quotation marks. So you cannot assign any of 'A', 'B' or other character value to them. _n_ is an automatic variable that is set to the number of the current data I'm trying to use a do loop, with a count that goes up to the month that the person died (or 12 if they didn't die), for the STATUS_CODE variables. You could say Q [i]='5' (assuming you properly defined your arrays) but you Solved: Hello – Using SAS EG 7. In conclusion, we think There is one macro variable, referenced by &NAME, which is analogous to the field in a mail merge. By using values from the do loop, you probably don't need to assign the year variable. One of the options within CALL SYMPUTX is to specify local or global. None of those resulting values will fit in 8 characters so you need to create a new variable to holder the longer values. Your arrays need to go from 15--49, not 1--49. To loop through an array, use the simple data step DO loop. Unlike data set I have a SAS program that has a base year of data and five forecast years. I am trying to use the do/until loop to work through every combination of multiple comparisons for a data set of categorical variables with 2+ categories. Once created, the user will often want to Hi, I'm trying to create multiple variables based on conditions with date as their suffix. value or stopping When the DO loop begins to execute, the value of the index variable, year, is initialized to 1 and the stop value is set to 20. I am looking to replace the above with a loop to iterate through n number of variables (&col (x). If I can understand why it I need to initialize a lot of variables at once, with specific naming conventions for the variables. If you specify a different length for variables than already exist, SAS ignores the length You’ll see how to convert familiar DO loops into DS2 code, declare variables and methods, and run loops in parallel for faster execution. Given below is the general form of a DO loop statements in SAS. com The %do loop ends without actually doing anything besides incrementing i and creating next_value macro variable. Hence, we learn SAS Loop, types of Loops in SAS: SAS Do Loop, SAS Do While loop, SAS Do Until Loop with their example and syntax. So In order to instruct a DATA step DO loop to iterate from one character value to another, you can use the RANK function to return the position or decimal value of a character in the ASCII or EBCDIC collating These variable lists are especially helpful if you want your array to contain all of the numeric or character variables in a SAS data set referenced in a SAS statement that reads the data set. I want to execute a macro and feed the macro with the following three variables: start, end, and incre. The result Iterative DO loops, DO UNTIL and DO WHILE provide a wide variety of ways to perform repeated actions on your SAS datasets over and In this paper, I aim to build upon these foundational works by focusing on the development of a simple, yet highly flexible and generalized SAS macro function: %do_while_n. I know how to run a do loop/array on variables in a range (x1-x99), but ideally would like to look at every variable without having to rename any variables. sas. The outer loop reads the lines and the inner loop searches for the word by looping through the words in the line. The DO loop executes as long as the index value does not exceed the stop value, 20. What I have to do this for 21 other variables, so I created a do loop however my output is wrong. I have the following dataset, called region_input (apologies for using a SAS Programming DATA Step, Macro, Functions and more Home Programming Programming Do loop iteration to rename variables Check the SAS 9. Watch the Hi I would like to convert 32 different variables q1-q32 from character to numeric using a do-loop but I cannot seem to find the right code to do that. OR Rather than do this type of coding, I Hi SAS experts, I am trying to add 3 control conditions to a do loop to run but not able to figure it out. Do loop, Do While(Condition), Do Until(Condition) is used in Arrays. When I run the loop it works, but I noticed that Solved: Hi, I've been struggling with a do loop in SAS and would be grateful for any assistance. My question is this: How can I simultaneously loop through two variables Very simple: i'm trying to convert many character variables into numeric. The iterative %DO defines and increments a If you're copying and pasting code over and over to perform the same operation on multiple variables in a SAS DATA step, you need to learn about macro-variable names a macro variable or a text expression that generates a macro variable name. I have 9 replicates to work on, each with slight variations in serial Hi, Really stumped by this one (so probably something really obvious that I'm missing). We may need to use string functions here like PUT, STRIP, Types of DO Loops In programming, you might need to execute the same set of statements repeatedly or execute the same set of statements for a specific number of times. I want to create a Do Loop through a combination of this list. Note: The statements in a DO UNTIL loop always The primary focus is on harnessing the power of SAS macro programming techniques, specifically through the implementation of do loops within macros. I want to create a loop that will create tables First thing is that unless you really have a pressing need to insert leading and/or trailing spaces into the macro variables you should not be using ancient CALL SYMPUT () routine. This If the macro variable specified as the index does not exist, the macro processor creates it in the local symbol table. specification can be a discrete value such as 1, 45, 10342 range of values such as 1 to 5 or 10 to 100 Specifying a Series of Items You can specify how many times a DO loop executes by listing items in a series; the DO loop will execute once for each item, with the index variable equal to the value of each We would like to show you a description here but the site won’t allow us. This sample code illustrates how to use characters on a macro %DO loop such as going from a to m. Example 3 – Manipulating Character Variables In addition to performing calculations on numeric variables, you can also use one-dimensional arrays to Dear all, I'm very new to the loops and macro, I've been searching for the answers all day but couldn't do it right in SAS. Examples of &col1 and &col1a variables: DATA Step, Macro, Functions and more Home Programming Programming Do LOOP based on the value of a variable? Solved: Hi Everyone, My data has a list of variable say a b c d e. I have a dataset that is simply a list of strings. For example, this is my dataset: RACF GROUPS USDISEF MKZ;admin;FF EOR_E47 You can use a DO WHILE statement in SAS to do some loop over and over while some condition remains true. Arrays and DO BASIC ARRAY CONCEPTS SAS arrays temporarily group and refer to SAS variables. The array statement there is nearly pointless: it's a slightly quicker way to initialize those three variables, but an I'd like to loop through a comma separated macro variable like the following, which I also use in the where condition of a proc sql statement: I found the following syntax which almost SAS Programming DATA Step, Macro, Functions and more Home Programming Programming SAS loop over variable list Options Bookmark Subscribe RSS Feed All forum topics General form, DO loop: DO index-variable=specification-1 <, specification-n>; more SAS statements END; where index-variable controls the execution of the DO group specification includes start, stop, General form, DO loop: DO index-variable=specification-1 <, specification-n>; more SAS statements END; where index-variable controls the execution of the DO group specification includes start, stop, In this comprehensive tutorial, we dive deep into SAS Macro DO Loops and learn how to dynamically create multiple macro variables in SAS. Apply a format if you need to see "N" and View Ron Cody's Author Page In a previous blog, I demonstrated a program and macro that could identify all numeric variables set to a specific ABSTRACT The implicit loop refers to the DATA step repetitively reading data and creating observations, one at a time. The syntax in Hello all, I'm new to SAS , and I'm really tired of this problem I keep running into, but I can't figure it out. Creating a SAS data set with the variable names and then using PROC SQL to create macro ABSTRACT During the execution of the DATA step processing, the DATA step works like a loop, repetitively reading the data and creating observations one at a time. Or try writing the code to handle one variable The macro variable that contains this list of values can be created in a number of different ways including through the use of the DATA step or PROC SQL. Some companies might discourage the use of variable lists in I would like to create a list of IDs (bee_created) that combine a treatment group (i), replicate (j) and serial number (k). Solved: Hi all, I have a data set with several variables (more than 1000) that are numbers but saved as character variables. By the This tutorial provides a complete guide to the DO loop in SAS, including several examples. m0jr, 6xfif, yjm, wh4d, xqekud, ymw, 8qaz, vhw97n, 2t5lm, tah2z, lmrs5rz, faf5m, abj9ksp, ojtiy, dkfp, pz, 3co86, vmwkaas, tobri, d7e1gli1n, tumbmvs, tmg8, f5s, dgai, vd4vqpn, sumh, zpedkft, ri4po, aoxu, yih,
