What I have been asking is, could they have defined the connection on
the AS/400 side as if they were talking to a workstation as opposed to
another "HOST"? I ask because after more than 10 minutes, things seem to
recover from a SNA viewpoint.

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...
