I am using the below step to check if the variables are not missing than concatenate. can i use these sec1 and sec2 in macro call because i dont know how many sec.. will be coming later.
if SEC1 ne '' and SEC2 ne '' then do; sec_r=catx(';', of SEC:);¨ end;

data _null_; counter = countw(sec_all, ','); do i=1 to counter by 2; sec_cat = trim(catt("&sec_at", scan(sec_all, i, ',')); end; run;

I am sorry, I don't follow you. The catx(';',of sec will concatenate all non missing variables with prefix sec together. I don't see where the need to use macro or check missing comes from? Please provide good examples - post test data in the form of a datastep and what you expect as output. Remember macro SAS is not a replacement for Base SAS, and doesn't do anything magical.
