Dear Marvin:


The  disease that  you observed  in AIM-176  is attributable  to line

printer senility coupled with user blindness brought on  by extensive

exposure to marginal output.  Fortunately, help has arrived.  Our XGP

produces output (e.g.  this page) with substantially  fewer glitches.

The only problem now is choosing among the 57 available type fonts.
