You should be able to return a value with a subprocedure.  This
support began in V3R2, so you should be able to do it at your
version.

Or isn't that what you mean?

example:

     D do_add          PR            10I 0
     D   parm1                       10I 0 value
     D   parm2                       10I 0 value

     D Result          S              7P 0

     C                   eval      Result = do_add(25: 31)
     c                   dsply                   Result
     c                   eval      *inlr = *on

     P do_add          B
     D do_add          PI            10I 0
     D   parm1                       10I 0 value
     D   parm2                       10I 0 value
     C                   return    (parm1 + parm2)
     P                 E
