Type: Adverb  (String*48)
Use:  To specify the name of some disk file outside the usual AIPS
      catalog system to be used as input to an AIPS verb or task.  The
      file can be a text file giving some list of commands or data to
      advise or enhance the task.  It is used when a second file is
      needed in addition to INFILE.
Format: The name is usually given by specifying a logical device plus
      directory, followed by a colon, followed by the actual file
      name.  Other combinations are often acceptable as well.  The
      logical name must be set up before entering the AIPS program and
      must be in upper case.  Thus, for Unix, for example:
              percent setenv MYAREA ~joeuser
      for the C shell, and
             $ myarea=$HOME; export MYAREA
      for bourne, korn, and bash shells.  Then in AIPS,
              percent aips tst
             IN2FILE = 'MYAREA:FITS.DAT'
      Note that the Unix-standard $ ahead of the logical is omitted.
      Other forms are now acceptable as well:
             IN2FILE = 'FITS.DAT
      will find the file in the $FITS directory (when reading or
      writing FITS disk files) or in the directory local when you
      started AIPS.  A full path name may also be given
             IN2FILE = '/home/primate2/egreisen/AIPS/Text.prt
      if it fits in 48 characters.  Note that the trailing quote mark
      is left off and this is the last command on the input line so
      that the case is preserved.

      AIPS-standard logicals like RUNFIL (AIPS/RUN area) and FITS
      (often AIPS/FITS) are available also.

Null value:  '          '
      Taken to mean no subsidiary file.  This can be an error.
