APLX
Revision as of 21:02, 10 September 2022 by Adám Brudzewsky (talk | contribs) (Text replacement - "<source" to "<syntaxhighlight")
APLX was a cross-platform dialect of the programming language APL, created by British company MicroAPL Ltd., as a successor to their APL.68000 product.
APLX is intended for uses such as financial planning, market research, statistics, management information, and various kinds of scientific and engineering work. APLX is based on IBM's APL2, but includes several extensions. It is available on Microsoft Windows, Linux, and macOS. Though APLX keeps APL's extended character set, APLX is a bit more verbose, due to the prevalence of system functions with long names, and the use of structured-control keywords. The use of explicit loops is a major deviation from earlier APL versions and derivatives.
Effective July 11, 2016, MicroAPL withdrew APLX from commercial sale. British firm Dyalog Ltd., authors of Dyalog APL, began hosting the APLX Archive website including the download area and documentation.
