Virtual Terminals and Data Queues

Simon,

I discovered this problem a few years back and thought it had been
fixed.  But I guess not...

What's happening is that the SenderId information is actually tacked
on to the *DTAQ message by the data queue APIs prior to the actual ENQ
instruction.  The Virtual Terminal support is using ENQ directly and so
the API logic never gets into the picture.

I would suggest submitting an APAR on this situation.
