There are a couple of ways to go about this, but I before you go too far afield
please describe what happend with SHOWCAT.  It really seems to fit your needs.
An alternative is to use SVC 26 (LOCATE), building your own CTGPL (forget about
CAMLIST), but this is a little tricky.  Better to debug your SHOWCAT program.
 
Mail me if you need help.
