When Conrad first posted, I noted it was a VTAM topic so I checked the
Communications Server SNA Customization manual.
> why is it not allowed to use WTOs in DSME-Exit?
You will find the following line in the "Design requirements" section for each
exit:
<quote>
Do not issue any SVCs if this exit routine is running in SRB mode.
</quote>
Well, now, the question now arises as to whether or not the exit runs in SRB
mode, does it not?
It turns out that only the USERVAR - most of the time - and DSME exits are
documented as running in SRB mode.
Thus Conrad has done his "due diligence" with respect to the DSME exit.

If this is an USERVAR exit or a DSME exit, you have bought defective goods.
Perhaps you can reclaim from your credit card company!

Not officially if the exit you acquired is the USERVAR exit or the DSME exit.

Actually, long ago when I had my education systems with which to play, I
wrote up all of the VTAM exits which existed at the time. Mostly what I did
was extract the information which is presented to the exits. Initially I used
WTO but that was such a mess on the console that I changed all the WTOs
to WTLs ("write to log" - is that an official macro or did I just create one
wrapped around the SVC?).
I believe I must have indulged in this exercise before the DSME exit was
available and so I can't comment on whether or not it might work - but
unofficially - and certainly not in a *production* system - if you want to be
supported ...
