Can anybody help me ?
I am trying to use the DCL command
"SET TERM/BRDCSTMBX"
but the documentation as to its full use and definition is very
limited. Am I right to assume that a mailbox must be created beforehand
and that $ASSIGN must then be used to associate the terminal with
the mailbox, thus allowing the /brdcstmbx command to be used ?
Once this HAS been set up, I expect all broadcast messages that
are normally sent to my terminal to be sent to the mailbox instead.
Am I on the right track ? Why not!!!
Thanx,
Jamie.

No, you do not have to create the mailbox first. All the /BRDCSTMBX
setting does is enable the reception of broadcast messages by a
mailbox associated with the terminal.
That is, if you associate a mailbox with the terminal (e.g., using
LIB$ASN_WTH_MBX), it will receive broadcast messages if the terminal
is set /BRDCSTMBX, and won't if it isn't. So set your terminal
that way all the time; there's no harm to it.
Just because a mailbox has been set up doesn't mean the messages
will go there instead of the terminal. Actually, the mailbox will
get *copies* of the messages. So the real best solution for handling
your own messages is to
save current state of /BRDCSTMBX
SET TERMINAL /BRDCSTMBX
run program that
calls LIB$ASN_WTH_MBX
saves the current state of /BROADCAST
calls $QIO and sets the terminal /NOBROADCAST, *OR*
calls LIB$SPAWN ('SET TERMINAL /NOBROADCAST')
does its thing
restores state of /BROADCAST
SET TERMINAL /[no]BRDCSTMBX (whatever you saved in step 1)
Of course, you could combine the setting and resetting of (/NOBROADCAST
/BRDCSTMBX) into two QIO operations in your program, which would
be the cleanest way because you wouldn't need a jacket procedure.
I recommend resetting the terminal state as part of an exit handler.

| 659.2 | Thanks. Is this in TFM? | ZFC::DERAMO | From the keyboard of Daniel V. D'Eramo | Thu Jan 28 1988 20:13 | 12 |
Re .-1:
Thanks. I wanted to know how to do this, too. Unfortunately, I
looked through VMSNOTES before thinking to try here, and here it
is already answered! My question now, is
How did you know that?
I found nothing in the io manual in the mailbox section, and
nothing in the on-line help for SET TERMINAL/BRDCSTMBX.

Try looking in the I/O Abuser's Guide in the terminal section, under
the TT$M_BROADCAST and TT2$M_BRDCSTMBX terminal characteristics.
(This is just a guess - I don't remember where/how I found out to
begin with!)
