[daip] problem with TV display

[Rob Willson]

Hi,
  Help!  I'm having a problem with the TV display for our (very old)
version of AIPS. When I try to load an image using TVALL, I get the
messages

ZXASOP: Channel assign error for LUN 9
YTVOPN: TV OPEN Error   6
TV Open ERROR 6

This version has worked for almost 10 years and it is the first time I can
remember this particular thing happening, Is there some papareter
somewhere that was inadvertantly set incorrectly? The TVCHAN parameter,
for example, is set to 1, which is what I think it always has been.

Thanks for your help!
