Hello
User define macro variable in structure as following:
1 or 2 digits number _4 digits number _ 4 digits number
for example:
%let X=59_2001_9901;
%let X=8_2001_9901;
I want to create another macro variable called Y that is created automatically from macro variable X and get the digits of macro variable X before the first underscore.
So in the examples :
%let Y=59;
%let Y=8;
May you show code how to do it please?
Use the SCAN function, wrapped in %SYSFUNC:
%let y = %sysfunc(scan(&x.,1,_));
Or even just:
%let y = %scan(&x.,1,_);
[EDIT:] Link to the doc. https://documentation.sas.com/doc/en/pgmsascdc/9.4_3.5/mcrolref/p1nhhymw6gxixvn1johcfl6kaygw.htm
;-D
%let X=59_2001_9901;
%let Y=%sysfunc(scan(&X, 1, _));
%put Y=&Y;
%let X=8_2001_9901;
%let Y=%sysfunc(scan(&X, 1, _));
%put Y=&Y;
?
