Hi,
I defined a macrovariable:
%let InDomainWhere=>"30DEC2021"D;
and I need in a %if condition to count how many characters are present, how can I do that?
I was currently using
%if %eval(%sysfunc(count(%cmpress(&InDomainWhere.),%str( )))+0) = 0 %then %do;
but I realized that it only counts spaces and not all characters.
How can I do this?
Thanks
Luca
Count how many characters are present: use the %length() macro function.
%if %length(&indomainwhere)=0 %then %do;
or if necessary
%if %length(%cmpres(&indomainwhere)) %then %do;
but if &indomainwhere is a date, I don't see why you would need %cmpres

You can use the %LENGTH() function to count the number of BYTES, which in a single byte encoding is the same thing.
If the string in the macro variable could contain UTF-8 characters then you will need to use the KLENGTH() function to count the number of CHARACTERS.
994 %let InDomainWhere=>"30DEC2021"D; 995 %let bytes=%length(&indomainwhere); 996 %let chars=%sysfunc(klength(%superq(indomainwhere))); 997 %put &=bytes &=chars; BYTES=13 CHARS=13
