VLAMODE
Type: Adverb  (String*2)
Use:  This string is used to specify the observing mode for VLA
data.  The following values are probably meaningful:
     '  ' => normal interferometer mode.
     'IA' => if you've used any of the others you may know what
             they mean
     'PA'
     'PC'
     'D '
     'TF'
     'VA'
     'VX'
     '1A'
     '1C'
     '2A'
     '2C'
     '4 '
     '4A'
Null value: none
Tasks:
   FILLR.....Reads old VLA on-line-system tapes into AIPS.  Mostly
             replaced by FILLM.
   FILLM.....Reads VLA on-line/archive format uv data tapes (post Jan
             88).  Also rerads older data that was converted to the
             "new" format.
