DOTABLE
Type: Adverb (Logical: <= 0 is false, > 0 is true)
Use:  Instructs programs to perform some operation with a table-
      like file.
Null value:  true (> 0).
Tasks:
   FITLD.....Reads FITS files to load images or UV (IDI or UVFITS) data
             to disk.  DOTABLE applies only to images and controls
             whether tables are written to AIPS disk.
   FIXRL.....Corrects right vs left polarizations for a list of
             antennas.  Most tables are just copied; DOTABLE controls
             whether SY, TY, and CD tables are modified.
   IMLOD.....Reads tape or disk files to load images to disk.  DOTABLE
             controls whether tables such a Clean components are written
             to disk.
   SWPOL.....Swap polarizations in a UV data base.  Most tables are just
             copied; DOTABLE controls whether SY, TY, and CD tables are
             modified.
