.lookup on the TT device problem

[Lee Gleason]

I wrote a slug of programs a while back for RT-11. Haven't needed to
look at them for a few years. Today, I need 'em again.


All of them assign a channel to the TT device (the console) via


tarea:: .blkw 5
tnam:: .rad50 /TT /
.blkw 6


.lookup #tarea,#6,#tnam ;open a channel to the console


This used to work fine. Now, when I run one of these programs, I get

?MON-F-No device 012620

I cut one of the program down to where I can tell that the .lookup
above is the offending line.

Not sure what that's telling me. I am not a skilled RT-11
programmer....Does anyone have an idea what could have changed in the
environment to cause this technique to stop working?

What are the details of the environment?

SHOW ALL

TT.SYS present? Installed? Loaded?

Thanks for the reply. Your question about TT.SYS gave me the clue I
needed to figure it out, TT.SYS had to be LOADed. It didn't initially
occur to me that could be the problem area, since the console was
working fine already, and I naively assumed that meant all was well with
the TT driver. Apparently on the RT11 system where I had previously used
these programs, TT had already been LOADed. This current one, it had
not. Clearly I have much to learn about RT11...

Thanks.
