RE: RPG/COBOL with embedded CL

Use an indicator in the LO position of the CALL to QCMDEXC.  This is just as
good as a MONMSG MSGID(CPF0000).  At least it's worked in my cases.  In
other cases where I'm doing a CHKOBJ or something that I will do a lot, I
make a service program out of it.  So something like:

C               eval    GoodObj = #Chkobj(ObjLib:Obj:ObjType)
 *
C               if      (GoodObj = 'Y')
 * blah blah
C               else
 * blah blah
C               endif

(note:  These could be combined into one statement, I know, but just for
readablility.)
