A '''one-liner''' is an APL program consisting of a single line of code. Creating such programs to perform various tasks, which might be considered a less precisely-measured form of code golf, was a popular challenge in early APL. The one-line constraint was significantly more limiting in this era, as it prevented creating defined functions or using...")

The first such standard, ISO 8485:1989 was based on APL.SV, supporting only simple arrays. Later ISO/IEC 13751:2001, based on the nested dialect APL2, was published. Some modern dialects, such as APLX and GNU APL, are based on this later standard, while others, such as APL+Win and Dyalog, have a slightly different set of quad names and provide the migration level function...")
