<SNIP>
Steve -

The ability to recover within the APPC program is application-specific -
It really depends on how the program is written and how it handles
recovery when the communications link fails.

I haven't written an APPC program since 1992, so I'm a bit rusty on the
programming aspect of it.

However, I'm looking at my 1992 code right now:
You create DDS and from it you create a communications file (CMNF), and
(if you didn't know better) from looking at the RPG or COBOL program
that uses it you might think the communications file is a display file,
since in the RPG program the communications file is defined as a WORKSTN
file.

The AS/400 program would have to check to see if an error occurred on a
write or read, and take the appropriate action...

Thank you. It is as I suspected.

Steve Thompson
