If one invokes START_AIPS (usually by ln -s with name aips in
$SYSLOCAL) with no arguments, then you have told aips to guess where
you are and to run XAS on the computer it finds.  If sun32 does not
have an aips XAS to run then this will not work.  I suggest that you
read the aips man page either as a man page, or as Chapetr 2 of the
CookBook, or as HELP AIPS inside aips.  That explains the command line
arguments.

For X terminals and architectures for which you do not have an aips
system, one would usually run by setting $DISPLAY to point at the
display machine and telling aips to use unix rather than internet
sockets: 

aips tv=local

But read the full documentation - the caparmility is more than this.
