David,

In order to see a problem, you'd have to be doing two things
1) Writing to a file in PGMA in such a manner that RPG does blocking.
2) Writing some records in PGMA, then without ending the program or
closing the file, calling PGMB and expecting it to see the records
just writing by PGMA.

Regarding 1)
Basically, you have to write output only to a file. By default RPG
will block such output. Though you can use the BLOCK(*NO) keyword on
the f-spec to change it. In addition, the SEQONLY param of OVRDBF can
effect blocking.

You'll see a compile time diagnostic message:
RNF7086 - RPG handles blocking for file XXXXXXX. INFDS is updated only
when blocks of data are transferred.

Here's some more info:

In addition, Google is your friend.

HTH,
Charles Wilt

That's an interesting piece of information that I'm saving so that I'll be able to use it next time, but I'd like to know when to implement it. I mean, do we HAVE to discover the problem during the test or wait for a program to crash or not work properly first?

I'd use FEOD with the N extender.  i.e. FEOD(N) filename;

This version is far more efficient than even the basic FEOD
and better than removing blocking. Its effect is to write the
current updated block back to the OS buffers so that it is
immediately visible to other programs - it just doesn't force
the system to wait while the data is written to disk.

Avoid closing the file whenever possible.

Yes, closing the file should force it to disk.
Likewise, you could use FEOD (without closing the file) Or
you could
put BLOCK(*NO) on the F-spec.
