How to drop variables if variables' name contain certain character

[hhchenfx]

Hi Everyone,

So I have a long list of variables and I only want to keep (or drop) all variables with "Jan" or "jan".

Any help is very much appreciated.

data have;
input Jan1 _1_jan Feb March_ ;
datalines;
1 0 0 0
2 1 1 1
;run;

proc sql;
     select distinct name into :names separated by ' ' from dictionary.columns where upcase(memname)='HAVE' and upcase(libname)='WORK'
     and upcase(name)?'JAN';
quit;

data want;
    set have (drop=&names);   /* OR set have (keep=&names); */
run;
