Frederick Way, of Case Western Reserve University, has constructed
this editor using J. It uses the "/" and "," conventions known
to some APLers. Here is Fred's (edited) letter.

VOILA!!!!
A trivial "/" (delete character) and "," (insert text) editor for J
that seems to work:
L0=.'$.=.s#$.}:s=.0 0 1 1 0{.~3*_1+2*0=#inp=.1!:1 (1)}:y. 1!:2 (2)'
L1=.'y.=.(/:(i.#y.),($cac)#inp i.'',''){y.,cac=.}.inp#~cv=.+./\inp='','''
L2=.'$:(-.''/''=(#y.){.(-.cv)#inp)#y.'
L3=.'y.'
edit=.(L0,L1,L2,:L3) ::''
Holiday cheers,
Fred
