The font used by the MacFORTH system source editor has the same kinds
of ambiguities:  capital "O" and digit "0" are exactly identical;
capital "I", small "l", and vertical-bar "|" are exactly identical.
Not real great for programming in a language where any character can
appear in any context!  I would love to modify that font so that every
character has a unique appearance (aesthetics are clearly secondary).
The font is one of the standard (first release) Mac fonts -- the
only non-proportional sans-serif font in the set (12-point Monaco? --
I don't have a Mac handy to check now, and I never can remember which
font name goes with which font).  But how do you modify a font?
Using FORTH, I can twiddle any bit in memory or on the disk, but how
do I find the right place?  I don't have access to a Lisa cross-
development system.  Any suggestions?
