I have a large base of software in ucsfcgl APL, 4.1, and I've just started
looking at Purdue 4.2 APL to see about converting to it. To my horror I
discovered that Purdue APL deals only in overstruck characters or real APL
characters. Having spent the last 10 years using various APL systems on
3 different computers in which rho was .rh and iota was .io and quad was
.qd, I'm quite reluctant to switch to a scheme in which quad is L <bs> \
and lamp is J <bs> C. Backspacing and overprint just looks funny on my
CRT.

Purdue supplies some screwy editor called XED, which I assume offers some
way of editing overstruck characters on a CRT. I don't want to use XED,
I want to use emacs.

I'm preparing to solve this problem by some combination of an emacs special 
mode, pre- and post-processor programs to do the conversion in and out of
emacs, or even modification to the character translation tables of apl.
Before I get started, I'd like to know if anybody else out there has faced
this problem and if so, how they decided to solve it.
