RE: ovrdbf SHARE parameter

You said (paraphrasing since I don't have the original here)
that CLP (which I hope is actually CLLE) does: OPNQRYF
followed by CALL TESTPGM... and TESTPGM uses the same filename.

Dennis,
Here's what I wrote originally,

CLP
OPNQRYF (myfile) with kfld changed from 5 to 3 kflds.
call testpgm

testpgm calls mypgm which also uses myfile and the 5 original kflds.

Obviously, the opnqryf must be changed, but how should we have done it?
<<<<<<<

CLP, (not CLLE!) does the OPNQRYF and calls testpgm(the program my
coworker was testing) as it has done for several years.
A subprocedure called by testpgm now calls mypgm.

You failed to answer questions about OVRSCOPE and OVRDBF but I'll assume
that, one way or another, the OVRSCOPE(*JOB) was used, and that SHARE(*YES)
has been specified.

In mypgm, the file used in the opnqryf is declared. Thus, as I have
learned from the experts during this thread, mypgm will not open a new
data path, but share that of the opnqryf.

We have addressed the fact that ODP will not be implicitly shared.

However, a subprocedure in
mypgm issues a chain to myfile, using 5 keyfields. The opnqryf
specified 3 kflds and the program crashes with the message that I'm
using too many fields to access the file.

One solution to this would be to use a different filename (and different
OPENID) for the OPNQRYF. That would involve a change to MYPGM and to the
OPNQRYF command. Another would be to use consistent number of keys (5). If
the three keys you are using in MYPGM are not the same as the first three
keys used by TESTPGM, you are asking for trouble unless you use different
names. If they ARE the same, however, then a change to 5 keys in OPNQRYF
sounds like a right solution.

Having said that, you know (and we don't) how these files must be accessed.
We can make recommendations until the stars all fall, and still be dead
wrong since the only thing we know about your goal is that you want to
understand override scopes.
