Chapter 8  OUTPUT
 
TD produces the following output:
     1.  Plot  - This may be on your terminal, LPA0:, another terminal, or
         a file on disk.  The plot data format and file is modified by the
         command:
              TD:SET DEVICE
         Plot output for a device other than your terminal is a file whose
         name matches the input file name,  and  whose  type  is  assigned
         according  to  the  device.   If there is no input file name, the
         output file name  is  UGDEVICE.   You  can  define  logical  name
         TOPDRAWER_OUTPUT to specify a name of your choice.

         File types are:
             CAL  - Calcomp Microfiche
             HPGL - HPGL
             IMG  - Imagen
             PS   - Postscript
             PTX  - Printronix
             Q    - QMS
             REG  - Regis, Gigi, etc.
             SIX  - Sixels
             TEK  - Tektronix
             VEP  - Versatek
             XCL  - Talarix EXCL

     2.  Listing - This lists all TD commands you used in a session.  This
         is normally TD.LIS, but the name may be changed by the command:
              TD:SET FILE OUTPUT 'newfilename'
         If you do not want a list file:
              TD:SET MODE LIST OFF
                   or...
              TD:SET FILE OUTPUT NL:
     3.  Journal  - This file contains all commands entered interactively.
         It is normally file TD.TDJ, but the name may be  changed  by  the
         command:
              TD:SET FILE JOURNAL 'newfilename'
         You may temporarily turn off journaling by:
              TD:SET MODE JOURNAL OFF
     4.  Errors  -  A  temporary file TOPDRAWER_ERRORS.DAT is used to save 
         the error messages for the  current  plot.   This  file  is  only
         opened for interactive sessions.
     5.  Data  - You may use the LIST command to output data sets suitable
         for input to TOPDRAWER.  If you do not specify the output file it
         goes to the Listing (TD.LIS).
