Can we help it if the PC is a "brain-dead" kind of machine and has no
other way telling when it gets to an "end of file"????

This is purely a kludge to get around a limitation on the PC.  It is
especially apparent when you see a ^D not only at the end of a Postscript
file but also at the beginning!!!

The postscript printer that is hooked up to our Unix system does not like the
^D at the beginning of the file and so we have to filter all the files that
come from a PC before they can be printed.
