I do miss MPE!
I used to use the JOB statement interactively, to test batch processing.
It was common for me to write MPE processes that checked that bit
returned by the WHO MODE, and then program logical decisions based on
running in batch or not. Later I found that it made more sense to use
the interactive bit instead. One particular company I worked for long
ago had a process run in a udc with the logon option to check both bits,
and not allow BATCH and INTERACTIVE to be true. I'm NOT sure why HP
would code that into the MPE operating system, but maybe they did. I
recall an old HP application know as MM that ran in BATCH and
INTERACTIVE, where each terminal session was a child process of a main
batch job..

Anyway James, your memory is not failing you, there was a time when you
could do that!
I Haven't tried it in a longtime, so I too am not sure when or if that
has changed.

I only bootup my HP3000 when I have HP3000 stuff to do, not so much
lately :-(
Lots of Windows and Unix stuff to do nowadays!

MPE had so many features like this, that worked so well for business
applications.
To the people responsible for killing the MPE operating system: You (all
of you) did a bad thing!

On MPE I could check this like
IF HPINTERACTIVE THEN

On Unix it looks more like
if tty > /dev/null 2>&1; then

It may not even be an option on Windows.
