QuadAV Considered Harmful -- Still
[This article originally appeared in the ACM SIGAPL Quote Quad, vol.21, no.1, September 1990.]
The APL character set has contributed, more than any other facet of the language, to its lack of acceptance in the computing community at large. The character set is a metaproblem -- not a problem in and of itself, but a creator of other recurring problems of hardware, software, ergonomics, and psychology. The adoption of new, ASCII-base dialects of APL, such as J, is suggested as one solution to the character set problem.
