Hello:
I got an error message while running macro. Please help. Thanks.
%macro rename(oldprefix, newprefix, num);
data want1;
set test;
%let k=1;
%do %while(&k <= &num);
rename &oldprefix.&k = &newprefix.&k;
%let k = %eval(&k + 1);
%end;
run;
%mend rename;
%rename(nad_dx,bd_dx,%cmpres(&cnt1.));
WARNING: Apparent symbolic reference CNT1 not resolved.
Nowhere in that code is the macro variable CNT1 defined.
