RE: Alternatives to build a LF on the fly

Can you use a CL program that creates an opnqryf over your file, then, still
in the CL, override your program's file name to the opnqryf? That should
work I believe.

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.
