There were NO Y2K problems that affected anything serious and the old
DATE strings are recognized and handled.

I cannot speak for 15APR91 - the FITS writers may have left out things
although I would be suprised if something as basic as simple tables
would be left out.  There are translation problems from some of the
older table formats so that they might not work well although
automatic translators are built in.

Th uv problems are very strange indeed.  Rather than LISTR, try PRTUV
on the data before running INDXR.  Also run PRTTP on the FITS disk
files beforehand with PRTLEV set to 2 and send me the results.
