'''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. APLX version 3 was released in April and May 2005. 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]], authors of [[Dyalog APL]], began hosting the APLX Archive website including the download area and documentation.
