The file in this case would be a 16 byte files whose first byte had value 2
(control-B), 2nd byte had value 7 (control-G), 3rd byte had value 4
(control-D), etc.  The usual procedure would be to create such a file on a
mainframe and then do a binary download to the Mac for use in Contours (or
other NCSA visualization software).
