 Function

  IEXP alternate file flags (valid flags = GRAPH, SEC, LANG).

 Syntax
  DISPFILE file,flags

   file   - A string expression with the file name (or base file name)
            to display.
   flags  - An integer expression with alternate file flags.

 Remarks
  This statement will allow you to display a file to the user, and
  optionally to have PCBoard look for alternate security, graphics,
  and/or language specific files.  The flags parameter should be 0 for no
  alternate searching, GRAPH (1) for graphics specific searching, SEC (2)
  for security specific searching, LANG (4) for language specific
  searching, or any combination thereof for multiple alternate searches
  simultaneously.  Alternatly you can use the three predefined constants
  to specify each flag:

    SEC     Security level specific file search flag
    GRAPH   Graphics specific file search flag
    LANG    Language specific file search flag

  To use these flag constants simply add the ones you need together.
