HELP SECTION

REFDATE
Type: Adverb  (String*8)
Use:  Data from which all times in a uv data set are counted.  It must
      be the lowest day number in the data set - i.e., get it right.
      Task FXTIM can be used to repair a data set for negative times.

Format: 'yyyymmdd' should be used.  The old 'dd/mm/yy' is usally
      accepted but is deprecated.
Null value:  '      '
          Null => use the first one found.
Tasks:
   FILLM.......Translates VLA on-line data to AIPS uv format.  Default
               is usually safe.
   MK3IN.......Translates MkIII VLBI data tapes to AIPS uv format.
               Default often gives wrong results since data are often
               not in time order.
   UV2MS.......Appends single-source file to multi-source file.  Be
               careful with the default if more data are to be appended
               later.
