Re: OVRDBF doesn't seem to be working

The reference by the program to APDTLWK2 would only be during compile-time; i.e. there is no requirement at run-time that any file named APDTLWK2 exist anywhere on the system. Anything the program would need to know about that file at run-time should have been established by the HLL, stored within the compiled program object; an effective rules-list is generated for how the file is to be opened. The FILE() named on OVRDBF is just a label for reference, and need not name any actual object of type *FILE. When the file name APDTLWK2 is referenced by a program, that name [label] is searched in the Common Data Management list of overrides, and the override is applied to that open if an entry by that name\label is located with the proper scoping. Whether the named TOFILE() has the necessary attributes to be compatible with how the program was compiled, that will be determined in part by the Common DM Open [e.g. lvlchk, existence, allocation], then some more by the Database Open [e.g. is keyed], each in response to the compile-time rules established from both the file declaration to the HLL and the file definition\attributes extracted during the compile [which also could have been directed to another file name by an override to database file request]; then I suppose the HLL run-time might do something to further ensure compatibility.

Because you've done an override from APDTLWK2 to &FILE the program
has to reference APDTLWK2 instead of &FILE for the override to take
effect. Because &FILE has a different key that APDTLWK2 if AP340 is
compiled over APDTLWK2 then I'm not sure that override will work.

What's the code in AP340 look like that references APDTLWK2
and &FILE?

The OVRDBF command below doesn't seem to be working. APDTLWK2 is
a logical file keyed on Vendor Name and Invoice Number. When AP340
(simple print program) is called, the program uses the sort order
in&FILE (Vendor Number, Invoice Number).

Any suggestions?

OVRDBF FILE(APDTLWK2) TOFILE(*CURLIB/&FILE) +
OVRSCOPE(*JOB) SHARE(*YES)

CALL PGM(*CURLIB/AP340) PARM(&FILE)
