DOKEEP
Type:   Adverb  (logical,  > 0  =>  true)
Use:    Tells a task or procedure to keep something
Null value:  false (<= 0).
Verbs:
  BDF2AIPS.......Read EVLA ASDM/BDF data into AIPS.  DOKEEP causes
                 online cal data to be kept (not a good idea usually).
Tasks:
  FITLD..........Reads FITS files to load images or UV (IDI or UVFITS)
                 data to disk  DOKEEP > 0 causes fully flagged
                 visibilities to be retained.
  FQUBE..........Collects n-dimensional images into n+1-dimensional
                 FREQID image.  DOKEEP true syas to retain fully blanked
                 or missing m-dimensional images.
  PCLOD..........Reads ascii file containing pulse-cal info to PC table.
                 DOKEEP true says to keep records that are not in any
                 scan.
  RLDIF..........Determines Right minus Left phase difference, corrects
                 cal files.  DOKEEP causes every SOLINT solution to be
                 written in the PP table.
  SLICE..........Task to make a slice file from an image.  DOKEEP says
                 to make simple slices stay in input pixels rather than
                 being heavily interpolated.
  SNREF..........Chooses best reference antenna to minimize R-L
                 differences.  DOKEEP says to retain all "temporary"
                 SN tables (each with different referance antenna).
  UVLOD..........Read export or FITS data from a tape or disk.  DOKEEP
                 > 0 causes fully flagged visibilities to be retained.
  VHDIF..........Find/apply V minus H linear polarization phase
                 difference.  DOKEEP causes every SOLINT solution to be
                 written in the PP table.
  VLBSY..........Reads ascii file containing VLBA total power info into
                 an SY table
  XYDIF..........Find/apply X minus Y linear polarization phase
                 difference.  Replaced by VHDIF.
Procedures:
  IMFRING........Large image delay fitting with IM2CC and OOFRING,
                 DOKEEP true says to keep the divided data set.
  IMSCAL.........Large image self-cal with IM2CC and OOCAL.  DOKEEP
                 true says to retain the divided data set.
  OOCAL..........Self-calibration with spectral-dependent corrections
                 for primary beam and spectral index.  DOKEEP > 0 =>
                 keep the data set which is the input data divided by
                 the model.
  OOFRING........Fringe fit data to determine calibration with spectral
                 index options.  DOKEEP causes divided data set to be
                 kept.
