DOIFS
Type:  Adverb     (Logical,  > 0  =>  true)
Use:   Controls functions done across IF numbers
Null value:  false (-1).
Tasks:
   FLAGR.........Edit data based on internal RMS, amplitudes, weights.
                 DOIFS > 0 => flag all IFs if one is bad.
   KRING.........Fringe fit data to determine antenna calibration,
                 delay, rate.  DOIFS controls how IFs are combined in
                 the solutions.
   PLRFI.........Plots spectral statistics from output of VBRFI & VLBRF.
   RLDLY.........Fringe fit data to determine antenna R-L delay
                 difference.  DOIFS controls how IFs are combined in the
                 solutions.
   SNFLG.........Flags uv data based on jumps in an SN or CL table.
                 DOIFS true means to flag all IFs when one is bad.
   VPFLG.........Resets flagging to all or all corss-hand whenever some
                 are flagged.  DOIFS controls how much is flagged when
