A few historical implementations of APL are very interesting. The Burroughs 220 version by Larry Breed was the defining factor of what became the APL environment. Jim Ryan's APL for the Burroughs 6500 was nothing short of amazing and pioneered many of the performance enhancement mechanisms now used in production optimizing compilers. John Walters (ex-IBM) built an APL compiler for HP which compiled very good code but retained the interactive character of APL. Much of the early history is documented in the ACM Quote-Quad.
- nigwil_ 11y agoThe user manual for Jim Ryan's APL\700 implementation is here: http://www.softwarepreservation.org/projects/apl/Manuals/APL700UserReferenceManual/view http://www.softwarepreservation.org/projects/apl/Manuals/APL... If we can get a working Burroughs B6700 emulator (see elsewhere in this thread) we may have enough pieces to see APL\700 working again. We're seeking the APL\700 Installation Manual (Form 5000805) if anyone has a copy. Note the use of the "\" in the name was intentional according to Jim Ryan, "APL "expands" the '700 series" (comp.lang.apl) As drallison notes, APL\700 was a compiler to an intermediate language.
