Question

I have observations that have 1 dollar signs ($), and observations that have 2 dollar signs ($). I want to assign different values to each type of observation. It should look something like this:

“$200 $300” gets assigned 1.
“$200” gets assigned 2.

I’ve tried playing with Perl wildcards all day but no luck.

Thanks.

Answer 1

How about the SAS countc() function to count the number of times ‘$’ appears?

%put %sysfunc(countc($300 $400,'$'));  /* returns 2 */
%put %sysfunc(countc($300 ,'$'));      /* returns 1 */
