RE: DSPFFD with KeyList

[Joe Giusto <JGiusto@xxxxxxxxxxxx>]

Build a DSPxxx in a library of your choice, then build a logical over
that file (DSPxxxL1).  use the logical in your RPG pgm to compile.  In
the cl, CRTDUPOBJ of the DSPxxx and it's logical to QTEMP.  then run the
DSPFFD to the PF in QTEMP.  OVRDBF DSPxxxL1 QTEMP/DSPxxxL1.  CALL
RPGPGM.

Altenately, if it is just the sort order that you want, leave QADSPFFD
in the RPG as an IP without the K.   then OVRDBF QADSPFFD QTEMP/DSPxxx
SHARE(*YES).  OPNQRYF QTEMP/DSPxxx ...   CALL RPGPGM.
