Re: clearing file currently opened in exit pgm

:) Didn't say you didn't, merely offering a suggestion. The behavior you're
experiencing looks like a rollback has taken place.

COMMIT is a job/activation group function used to signal a transaction made
up of multiple CRUD operations is complete. It's not issued against a
file: the idea of COMMIT is to maintain the integrity of the transaction
across multiple resources. Extra credit if you know the meaning of
"ACID"!

Use COMMIT/COMMIT WITH HOLD (if SQL) in your program and the changes to the
resources opened under commitment control will be made permanent.

Just saying.

I know how to do commitment control in rpg for PF’s (both native and
sql)...

But what is the rpg syntax to issue a commit on a stmf?

if the file is journaled, you'll need to do a COMMIT.

So I have a stmf file opened in my exit pgm registered to
QIBM_QP0L_SCAN_OPEN.
I want to clear that file... and then later write to it further in the

exit

pgm.
I do a ftruncate64() in my exit pgm and if I do a wrklnk and look at the
bytes, it did clear it and set the bytes to 0.
Good...
But when I later write to the file later on in the exit pgm, the data I
thought I cleared returns and my new data appends to it.

Is this because the file was never closed before the new data was

written

to it?
How can I ensure it is cleared and then allowed to write to in this same
exit pgm without the ability to close it before the write?

Is there some functionality with the below exit pgmoutput ds fields that
can be set to allow my clear to "stick"?

8 8 CHAR(1) Update object scan information
9 9 CHAR(1) Scan status
