PRSSTY

       SUBROUTINE  PRSSTY (TYPE)
 C$    (Parse - Set Terminal Type)
 C$    Ideally,  it  should  be  possible  to  obtain  the  output
 C$    terminal type  from the  host operating system via  routine
 C$    PRSTTY.  If this is not possible, the user parsing  program
 C$    can use the support  routine PRSTRM to process  subcommands
 C$    for defining the  terminal type and  width.  If neither  of
 C$    these is possible, the terminal type may be set directly by
 C$    a call to this routine, where the INTEGER argument is:
 C$
 C$    TYPE.......-1 = not a terminal
 C$               0 = hardcopy or unknown,
 C$               1 = VT52,
 C$               2 = VT100,
 C$               3 = Televideo,
 C$               4 = Hazeltine-1500.
 C$               Other values are ignored.
