These are not tasks but verbs.  You can say either
tvlod
go tvlod
The latter will catch your error and translate to
tput tvlod; tvlod

But if you say
task = 'tvlod'
go
then aips cannot catch your grammar error until it is too late to fix it.

This message I cannot figure out.  To debug I would need you to cp 
$SYSUNIX/XASERVERS to $SYSLOCAL.  Then edit it to remove the comment 
symbols from the start of the two lines containing the string -hold.

Then when aips starts the message and tek server windows will remain up 
and we can see what appears in those windows.  Have you set the 
environment variable AIPS_MSG_EMULATOR to something other than its 
default xterm?  What operating system are you running?  Is there 
anything in your environment call vlines2?
