It would appear that your installation thinks there are no words in
the "pseudo array processor" used by many of the most important tasks.
Exit aips and do the following:

RUN SETPAR
2

look at the values for parameter 11 - which should be 64 and parameter
29.  I do not know what that value should be so try

29
99999

This will give you an error message such as

 *** Pseudo-AP 2nd memory limited to  5056 not   999999  

so enter whatever the first number is (5056 in my case).  Then

-1
AMANAGER                         (the usual password)
4                                (to exit)

Then try things again.

If the 5056 says 0 then you have a much larger problem.  In that case
the file $INC/NOTST/$ARCH/PAPC.INC has an error in it.  If this is the
case, send me the text of that file and I wil send you the lengthy
instructions for fixing your installation.
