XVIEW user defined buttons



  XVIEW allows the user to defined options which are set up

  as XVIEW buttons at run time.  These options are defined

  in a simple text file called xview.txt in the user's

  home directory.  Currently two types of options are supported,

  print and process.  The setup file has a simple format of one

  line per option:



	type: label text / comand or printer



  type is either the word print or process.

  label text is the text that will appear on the button so

    should not be too long.

  comand or printer can a printer number or substring of the

    printer description given by psinit,/list, or a command to

    be executed if type is process.



  Null lines and lines with * as the first character are ignored.

  An example setup file is



*------  xview.txt = user defined xview commands  ---------

print: Phaser 340 paper / Paper Color

print: Phaser 340 trans / Transparency Color



process: Negative / imgneg







  Note: if printer numbers were used the vivid color option would

  not work.  This option appears after the print command is requested.
