Re: Performance

Header spec has just datFmt and noDebugIO nothing special.
It seems like with each call to those SQL programs it's starting to
slow down inside those calls

When I compile i did not change any parms Would You like to tell which
specifically to check.
I can see this one  Allow blocking . . . . . . . . .   *ALLREAD  (that's
probably fine)

Thank You.

Well, the SQL is very straightforward. An index over abDateRcv, abWhse and
abNo _might_ improve the performance of the SQL, but if the statement
performs well in an SQL session, that is not likely to be the performance
roadblock.

How are the programs compiled, and what do the header specs look like?

If you make the two called programs into service program modules, the CALLs
might perform better. I would defer a detailed explanation of the advantages
of using service program modules, to some of the veteran ILE gurus on this
list.
