 Amy already suggested clearing any old TVs away and trying again.  I
cannot find any bug in the code that caused this (other than a brief
version of TVALL in the 31DEC04 version).

I would like to point out that we now have a way to install aips as 
LAPTOP='YES' which then uses LOCALHOST as the host name and saves you
from the interminable IP address changes.  Lots of other things have
been upgraded including making aips much easier to install (there is a
binary install even).  See the aipsletters at
         http://www.aoc.nrao.edu/aips/
for details.

Note that TVALL is a procedure.

  TVOFF(1234); GROFF(1234); GROFF(5678);
  J=GRCH;GRCH=8;GRCL;GRCH=J;
  GRCL;TVCL;OFFZOOM;
  TVLOD;
  TVON(TVCH);
  TVWED(16);TVWLAB;
  TVFID;

You could try running the latest form of it one step at a time to see
where it is failing but I suspect that it is at the TVWED(16) command.
