Small computer system supports large-scale multi-user APL

Another article from a very much bygone era – we’re talking 1977, and for sure this one’s a bit over my head. I like being honest.

APL (A Programming Language) is an interactive language that allows access to the full power of a large computer while maintaining a user interface as friendly as a desktop calculator. APL is based on a notation developed by Dr. Kenneth Iverson of IBM Corporation over a decade ago, and has been growing in popularity in both the business and scientific community. The popularity of APL stems from its powerful primitive operations and data structures, coupled with its ease of programming and debugging.

Most versions of APL to date have been on large and therefore expensive computers. Because of the expense involved in owning a computer large enough to run APL, most of the use of APL outside of IBM has been through commercial timesharing companies. The introduction of APL 3000 marks the first time a large-machine APL has been available on a small computer. APL 3000 is a combination of software for the HP 3000 Series II Computer System2 and a CRT terminal, the HP 2641A, that displays the special symbols used in APL.
