    I do not know quite what you have set up here so it is hard to
answer sepcifically.  Have you created an aips i9nstallation for a
single user on a single machine or are you attempting to create an
installation such as we run with 1 copy of aips but many machines
being used to run AIPS?

     There are two directories (at least) that must exist for a user
on machine XXX to run aips.  One is at $AIPS_ROOT/DA00/XXX which we
usually recommend to be actually on machine XXX.  This is achieved by
having the installation on XXX or by having the $AIPS_ROOT/DA00/XXX be
a link to a directory on XXX.  The files in that area are created and
initialized by RUN FILAIP on machine XXX.  If you installed aips using
machine XXX then these files should have been created near the end of
install.pl (FILAIP and POPSGN are the last 2 operations).  The files
in this area, known to a user on XXX, as $DA00 must be read/write to
the user.  They cannot be read only.  If you are making a many
machines installation, then the DA00 files are set up via the proc
SYSETUP XXX.

Normally I recommend using the directory $AIPS_ROOT/DATA to hold link
files such as XXX_1, XXX_2, YYY_1, YYY_2 etc which point to actual
directories on XXX and YYY which are on disks suitable for large
quantities of data.  Then the file $AIPS_ROOT/DA00/DADEVS.LIST will
contain lines giving the actual path (e.g. if $AIPS_ROOT is
/user/aips/install then)
    /user/aips/install/DATA/XXX_1
    /user/aips/install/DATA/XXX_2
    /user/aips/install/DATA/YYY_1
    /user/aips/install/DATA/YYY_1
The only thing these data area need to contain to make them available
to the user is a 0-byte file named SPACE over which the user has full
r/w privilege.

Since you deleted the original data area it is deleted.  But I assume
that it did not actually contain any real data so it does not matter.
