          RE:  New software to support the DIABLO
 
          The recently acquired DIABLO Letter-Quality printer has  several
          important  features that can be activated by sending certain ES-
          CAPE sequences to the printer.  For example, the following line,
          showing the use of half-line feeds can produce nice mathematical
          formula.
 
          Sample showing D superscripts U and U subscripts D.
 
          The full range of commands available is beyond the scope of this
          memo,  feel  free to peruse the operating manual for the DIABLO.
          Two modifications had to be made to avail ourselves of these ca-
          pablilities.
 
               1.  RUNOFF had to be modified to allow one to  insert  spe-
                   cial  characters  in  the  output  file.  The essential
                   change is that the character "@" is now a special char-
                   acter.   The  string "@33" tells runoff to put an octal
                   033 character in the output file.  The "@" character is
                   not  printed,  neither are subsequent octal characters.
                   Printing  is  resumed  when  RUNOFF  sees   the   first
                   non-octal  character in the input text.  Since "@" is a
                   special character, to print it you must preceed it by a
                   "_"  (underline) character to show that you really want
                   it printed.  Secondly, to avoid mass confusion to  cur-
                   rent RUNOFF source files, this is an option that is on-
                   ly evoked by a new switch.  The command of
 
                   RNO OUTFIL/SC=INFILE
 
                   tells  RUNOFF  that  your  source  file  has  "S"pecial
                   "C"haracter  generation code in it.  (Without the "/SC"
                   switch, a "@33" in the text will be printed and not af-
                   fect the DIABLO at all.)
 
               2.  The system will not  normally  let  you  print  special
                   charcters at the terminals.  To avoid this shortcoming,
                   a new program "DIABLO" is available.  DIABLO will print
                   files  at  the  DIABLO printer using special QIO'S that
                   let all characters pass.  its use is simple.
