     This runs an XASa on the sun computer with the $DISPLAY pointed
at your Mac.  If your LAN is very fast this is okay.  We set up things
differently so that there is a Mac version of aips as well as a Sun
(and Linux) all using the same shared $AIPS_ROOT.  Then XAS runs on
the Mac (or other desktop) and the compute server connects to it via a
socket.  Generally this us rather faster.

The adverb VERSION has gotten trash in it which is restored from the
LASTEXIT file.  Try VERSION=' '; INP whatever.  If the other adverbs
also appear trashed, do a RESTORE 0.  (Did you copy your data files
from one machine to another? - esp. one machine of opposite byte order
from the other?  Suns and Macs are the same big-endian order, Linux is
little endian.)

The message file for user 1 is used by service programs and when you
start aips but have not yet entered another user number.  If it is
missing the messages are lost but normally this does not matter at
all.
