To review the syntax of various DO, DO-WHILE, and DO-UNTIL loops in SAS, see "Loops in SAS. I tried creating do loop but not able to calculate character value in evaluating function. What I have is an array where individual data is organized by columns, e. 2. The macro facility does not allow character values on an iterative %DO loop. Before there was DO in all its forms there was GOTO. The patients in this table are unique and there is only one encounter per patient. I have a dataset with multiple periods, and for each period, I want to run a bunch of models. Sample 25961: Using character values on a macro %DO loop The sample code on the Full Code tab contains two macro techniques for iterating through character values in a macro %DO loop. For eg. ABSTRACT . Each time a PROC CORR step was generated, the %DO loop would automatically increment the AGE macro variable. Below is the code I have.

Learn how to use DO loops in SAS DATA step and SAS/IML language to iterate over parameters, indices, or values. Perhaps if you read the above paper and then Google for more papers on Macro processing (especially ones written by the most excellent macro guru, Art Carpenter), you will have a better idea of how macro variables and macro programs and macro %IF work and how they are different from a regular DATA step IF statement. Details; Program; Program Description; Logs. And do not manipulate the index variable of a %do (or do) loop inside the lop, as that skewers the incrementation, and you'll skip (or repeat) iterations. I'm hoping someone can give me a sample to work with, as I have been reading and experimenting to no avail. Aside: if you have "date" valu I will be inputting about 100+ cities. In the first example, the %DO is causing 12 statements to be typed for yousomething like this I am trying to use a %do loop in a macro, but it does not appear that I can increment by fractions.

It's best practice to always just define any variables local to that macro with a %local statement. In the code below, rather than saying %if &v. As I can't see what you intend, nor your data, at a guess: Seems to me you need a data step DO loop here and NOT a macro do loop, with the macro variables used to set the start and finish numbers of the DO loop. Join us for SAS Innovate 2025, our biggest and most exciting global event of the year, in Hi all, I'm trying to modify one of my code to a nested loop. sas. You could change the inner loop to : Hi, This is a data manipulation exercise. =5 or &v. One of the Since data step statements are not part of macro code, your macro loop is this: %do %until (&e = &nplus1); %let e = &nplus1; %let e = %eval(&e + 1); %end; and so the exit condition is never met, as &e will always be &nplus + 1. ; data want; set work. Dear Sas Community, I'm having troubles understanding why this code, with %str(;) inside of a sysfunc call in a loop is not working: %macro split_terms; %let terms = %str(This is a term; This is another term, with a comma; And this is a third term); %do i = 1 %to %sysfunc(countw(&terms, %str(;))); %put %scan(&terms, &i, %str(;)); %end; %mend; Hi, I have a macro to create several tables.

Join us for SAS Innovate 2025, our biggest and most exciting global event of the year, in Orlando, FL, from May 6-9. If you don't have working valid SAS code without macros and When a Macro PROGRAM executes, it is ONLY generating code based on the %DO loop(s) or %IF statement(s) in your MACRO program. Use do loop index in macro variable definition. Below is my code, any help woul be greatly appreciated %macro test; %do I=1 %TO 20; %if &I=1 %then Hi: The key to learning Macro programming is to have a good understanding of SAS programming first. Then when you have it working use the macro code (or macro variables) to replace the constant values. den(&i+1). The LEAVE statement exits a DO loop, usually as part of an IF-THEN statement to test whether a And you have some other macro variable that has a number, like 5, and you then want to run the loop 6 times? %macro month_loop(start_month,n); %Local offset basedate month ; %let basedate=%sysfunc(inputn(&start_month,yymmn6. There are two forms of conditional DO Loops, DO UNTIL loops and DO WHILE loops. All DO forms can be coded with GOTO, at the heart of those structures the much maligned GOTO is toiling away unseen. CONTINUE and LEAVE statements are just GOTO in with implied labels. Is there some way I can use the do loop index (buffer_number) to create the macro variables? Hello All, Below is the part of the code which I use to create different data set based on the macro variable 'cnt_crr_saa_limit' value using Do loop Hi all, I'm using SAS on Unix, that's the reason for the line numbers on the side. I am trying to increment by 0. Each variable takes the value of 0 or 1. ; . And want to use it in the data Next, you need to create working valid SAS code WITHOUT macros and WITHOUT macro variables for one or two cases. data retail2; set retail; %do quarter=1 %to 4; d&quarter=quarter=&quarter; %end; run; The logic that I think of is using a macro that performs a do loop using the difference of the max date in the text file that I have created and today()-1 as the end date.
