INFILE
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 command or for
      example, star positions or it can be a FITS file containing
      ASCII headers and binary data.
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
      is usually in upper case.  Thus, for Unix, for example:
             % setenv MYAREA ~joeuser
      for the C shell, and
             $ myarea=$HOME; export MYAREA
      for bourne, korn, and bash shells.  Then in AIPS,
             % aips tst
                  ....
             INFILE = 'MYAREA:FITS.DAT'
      Note that the Unix-standard $ ahead of the logical is omitted.
      Other forms are now acceptable as well:
             INFILE = '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
             INFILE = '/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.

      For VMS:
             $ def  myarea  disk$res:[joeuser.aips.files]
             $ aips tst
                   ....
             INFILE = 'MYAREA:FITS.DAT'
      but, also okay are things like
             INFILE = 'UMA0:[ERIC.IPOPS.JUNK]STARS.LIS'
      AIPS-standard logicals like RUNFIL (AIPS/RUN area) and FITS
      (often AIPS/FITS) are available also.

      Under UNIX, it is now possible to read and write tape files with
      other, cooperating computers.  If the other computer is running
      the AIPS "deamon" task TPMON, then INFILE may also take the form
             <node>::<logical>:<file-name>
      where <node> is the name of the other computer, and <logical> is
      a name known to TPMON on that computer.  This limitation
      probably requires you to use the $FITS or $RUNFIL or other
      widely known AIPS areas.  (For real tape, the node name is given
      in the MOUNT command instead.)  This option only applies to
      tapes (i.e. IMLOD, UVLOD, FITLD, TPHEAD).
Null value:  '          '
      Taken to mean no subsidiary file.  This can be an error.  For
      tapes, it means use a real tape drive given by INTAPE (which
      must already be MOUNTed).
Tasks:
