The  string is typed on your terminal.  This is useful for typing messages
on the users terminal while plots are being produced from an input file.
     1.  ERASE - This erases the screen (ANSI terminal).  This erases text
         from a VT-1xx/2xx  compatible  terminal.   This  does  not  erase
         TEKTRONIX graphics, but REGIS graphics will be erased.  This must
         be precede the string.
     2.  TOP - The string is at the top of the screen (ANSI terminal).
     3.  BOTTOM  -  The  string  is  at  the  bottom  of  the screen (ANSI
         terminal).
     4.  BELL - This rings the bell.
     5.  BOLD,BLINK,REVERSE,UNDERLINE,WIDE  - Sets the video attributes of
         the line.  These must be after the ERASE,TOP options  and  before
         the  string.   Several of these may be used together.  These only
         work for a VT-100 or compatible ANSI terminal.
     6.  BACKGROUND|FOREGROUND  control  the  color.  (ANSI terminal) Once
         the color has been set it remains set until another type  command
         sets new colors.
