== History == | |||
Raze was defined as monadic <syntaxhighlight lang=apl inline>↓</syntaxhighlight> in [[A Dictionary of APL]] in 1987, and added to [[SHARP APL]] in version 20, released in 1989.<ref>[[IPSA]]. [https://archive.org/details/sharp-apl-release-20.0-guide-for-apl-programmers "SHARP APL Release 20.0: Guide for APL Programmers"].</ref> It appears in [[J]]'s initial 1990 release as <syntaxhighlight lang=j inline>{.</syntaxhighlight> (that is, also paired with [[Take]]) but was moved to <syntaxhighlight lang=j inline>;</syntaxhighlight> in 1991.<ref>[[Jsoftware]]. [https://code.jsoftware.com/wiki/Help/Release/J_4.05/Implementation_Status J 4.05 Implementation Status]. Version 3.2.</ref> The glyph <syntaxhighlight lang=apl inline>⊃</syntaxhighlight> is used instead in [[A+]]. | |||
