HELP SECTION

TAPPE
Type:  Task
Use:   TAPPE copies a table version from the input catalog file and
       another version (of the same type) from the output catalog file
       into a third version attached to the output catalog file.  It
       then sorts the appended file and discards any rows that are
       identical.  The second and third version numbers may be the
       same.  Note that the sort plus test for identical may not be
       able to prevent some identical rows from appearing.  The sort
       is based on only two columns leading to potential situations in
       which identical rows do not become adjacent after the sort.
       Normally, this is unimportant and it should not arise in SN and
       CL tables where it might matter.  Note, however, if you append
       two SN tables that have differnt solutions for the same time
       and antenna, both solutions will remain in the output table.
       Unless you smooth such an SN table before applying it to a CL
       table (SNSMO and CLCAL offer this option), the two-point
       interpolation will be compromised.
Adverbs:
  INNAME......Main file name (name).       Standard defaults.
  INCLASS.....Main file name (class).      Standard defaults.
  INSEQ.......Main file name (seq. #)      0 => highest.
  INDISK......Disk drive # of image.       0 => any.
  INEXT.......Input extension file type    ' ' => 'TA'
  INVERS......Input extension file version # from INNAME
              0 => highest
  OUTNAME.....Output file name (name).      ' ' => INNAME
  OUTCLASS....Output file name (class).     ' ' => INCLASS
  OUTSEQ......Output file name (seq. #).    0 => INSEQ
  OUTDISK.....Disk drive # of output file.  0 => INDISK
                 where the actual values of INNAME, INCLASS, INSEQ,
                 and INDISK are used after defaults, wild-cards, etc
                 are satisfied.
  IN2VERS.....Second input extension file version # from IN2NAME
                 0 => highest
  BADDISK.....Disk drive numbers to avoid for scratch files.
