Charles, I guess I didn't make myself clear. I must use the same
program. Embedded SQL requires mods to the rpg code and that's not an
option.

If all you're doing is reading a subset of the records.  You'd be
better off using embedded SQL.

Hi group,

I have a CASE tool (2E) generated rpg program that reads a logical file
as input primary (READ loop). In some instances I need to run this
program against a subset of records only. I'm thinking of doing the
following at runtime in a CL program:

1) duplicate the physical file in QTEMP
2) populate with the records that I need to process
3) move QTEMP on top of the lib list
4) build another versionof the logical file in QTEMP (based on the
physical in QTEMP) using the CRTLF command
   CRTLF FILE(QTEMP/LOGICAL1) SRCFILE(SRCLIB/QDDSSRC)
5) setup an OVRDBF for extra safety and invoke the rpg program

I tested this and is working fine, but, I'm concerned with someone
making changes to the source file of the logical. Can anyone suggest

a

method to create the logical without using the DDS? If someone wants to
propose a different approach, I'm open to suggestions.

TIA
