Sample 36360: How to determine whether a macro exists within a SAS session
 |  |  |  |  |  |
This macro will return a yes or no depending on whether a macro has been compiled within the current SAS session. The way the code is currently written it will only work for those macros that have been compiled to the WORK.SASMACR catalog.
Pass in the name of the macro (minus the percent sign) you are searching for.
If the SAS session is created by a workspace server or running Enterprise Guide (EG)connecting through a server the macro code will need to be modified.
Currently the PROC CATALOG within the macro is looking in the SASMACR catalog but if running through a server the macros may be compiled and stored in a SASMACx catalog (where x represents 1,2,...). The code change would look something like this:
proc catalog cat=work.sasmac1;
contents out=new(keep=name);
run;
Starting in SAS 9.3 there will be a new function that will replace the technique described in this sample. It will be called %SYSMACEXIST.

else call symput('val','no');

%mend test;
/* Check for the existence of the macro test */
%test(test)
%put Does test exist: &val;
