I'm doing an OPNQRYF to limit access to certain records. The CL program works; but when a subfile is displayed, it includes records that I was trying to eliminate. Is this something peculiar to subfiles? This file contains records organized by Officer. I'm comparing the user ID to a cross-reference file to get the initials and then doing an OPNQRYF for those initials compared to the field in the file I'm accessing.

If you're getting records you don't intend to get, first make sure that the input file has the SHARE(*YES) attribute (see 6). People usually do this by overriding the database file before calling the high-level language (HLL) program.

If file XYZ is not shared, HLLPGM will not read the OPNQRYF file, but will read the file directly.
If that's OK, the next thing I would check for is errors in logical operators-*AND, *OR, *NOT. Are you using any of them in the QRYSLT parameter?
I would also check for errors with concatenation operators. For example, using *BCAT when you really need *CAT can make OPNQRYF retrieve the wrong records.
Check these things out. If you still have trouble, send another message and include that part of your CL program.

I know where you are coming from. In addition to Ted's comments, here's another trick I try. Once I run the OPNQRYF against the file, I will do a Copy From Query File (CPYFRMQRYF) command to a file in QTEMP. Then I will look at it with the Run Query (RUNQRY) command like this:
RUNQRY QRYFILE((QTEMP/file))
This gives me a picture of what data is being fed to the program. With me, nine times out of ten, it's the *ANDs and *ORs that give me a headache.
