David, the only way you can trap errors in CALLP in V3R2 is
to wrap the call in a subprocedure that has a *PSSR subroutine.
This technique can be used for any sequence of code that might
get an error.

D DoCmd           PR             1A
D   Cmd                       4096A   CONST
D   Len                         15P 5 CONST

C              EVAL   *IN99 = DoCmd('ADDLIBLE ASDF'
C                           : %SIZE('ADDLIBLE ASDF')


P DoCmd           B                   EXPORT
D DoCmd           PI             1A
D   Cmd                       4096A   CONST
D   Len                         15P 5 CONST

DQCMDEXC          PR                  EXTPGM('QCMDEXC')
D prCmdStr                    4096A   CONST
D prCmdLen                      15P 5 CONST

C              CALLP  QCMDEXC (Cmd : Len)
C              RETURN '0'

C     *PSSR    BEGSR
C              RETURN '1'
C              ENDSR

P DoCmd           E
