This means that there are no entries for his disks in the file
$AIPS_ROOT/DA00/NETSP and only really has consequence if the verb
TIMDEST should be (accidentally) used.

I guess the user's work station does not run aips so that the TV
displays cannot be on it - that is faster but this will work with a
high speed LAN.

The user is logged in to an account that does not have write
privilege to pre-existing files found there.  The file in the first
data area named "CAD000000.069;" (without the quotes) is the one that
is tested.  Some sort of open error (usually that open read-write
fails) occurred.  Data areas higher than the first may be read-only to
a user, but disk one is required to have write privilege.
