-----APL

[I_APL]
I-APL/PC (I-APL Ltd.; $0) is an implementation of APL. The author says more
can be specified in a page of APL than a page of any other language. I-APL
workspaces that don't use clock or machine code will load and run in any
I-APL computer with the same results. This APL interpreter conforms to the
ISO, BSI and ANSI standard for APL.

[SHARP]
Sharp APL/PC (I. P. Sharp Associates Ltd.; $59) is another implementation
of APL. Virtually no documentation comes with it, so you need to already be
familiar with APL.

[APLTOOL]
APL Tools (Church, Davin; $0) is a collection of APL*PLUS/PC tools.

[APLTEX]
AplTex contains C routines to read and write screen blocks in APL2.
