'''Rationalized APL''' is the name of a 1983 paper by [[Ken Iverson]] describing a [[backwards compatible]] extension to APL as developed by Iverson [[IBM]] (for example [[VS APL]]). Written following Iverson's departure from IBM to [[IPSA]] in 1980, it showcases Iverson's stance against the [[nested array model]] used by [[APL2]] and in favor of the [[boxes]] (here, [[enclose]]d arrays) already in use by [[SHARP APL]]. It was a precursor to [[A Dictionary of APL]] and many of the ideas it introduced were later incorporated into [[J]]. It also featured the [[Rank operator]], invented by [[Arthur Whitney]] the previous year, just prior to its inclusion in SHARP. | '''Rationalized APL''' is the name of a 1983 paper by [[Ken Iverson]] describing a [[backwards compatible]] extension to APL as developed by Iverson [[IBM]] (for example [[VS APL]]).
