I now know.  On the old system you told aips to use a single catalog
for all users and on the new system you have told it to use separate
catalogs for each user.  On the old system all files will have names
xxDnnnmmm\; on the new system they will be mostly be xxDnnnmmm.uuu\;
except for a few shared system ones.

You can

RUN FILAIP

and answer a positive number (e.g. +100) to the second part of the
first question.

Note, we normally recommend user private catalogs and the public ones
do not get tested all that much.  In fact our users on their desktops
often use multiple user numbers to separate projects.  With a public
catalog this does not work as well.

But to get the old data simply, it would be easier to change the
nature of this catalog - I suppose you could rename all the files
instead.  If the user used only one number that would work.
