The two [[glyph]]s commonly used for Disclose are [[Right Shoe]] and [[Up Arrow]]. The original [[NARS]] paper specified monadic <syntaxhighlight lang=apl inline>↑</syntaxhighlight> as Mix and <syntaxhighlight lang=apl inline>⊃</syntaxhighlight> as First, so [[Dyalog]] and [[STSC]] implemented [[Dyalog APL]] and [[APL*PLUS]] accordingly. [[IBM]] decided to swap them in [[APL2]], causing the others to implement [[Migration Level]], as APL2 was seen as the authoritative implementation. When the ISO [[standard]] was written, it closely followed APL2, causing [[APLX]], [[NARS2000]], [[GNU APL]], and [[ngn/apl]] to adopt these notations. However, ngn/apl later switched to follow Dyalog. | The two [[glyph]]s commonly used for [[Disclose]] are [[Right Shoe]] (<syntaxhighlight lang=apl inline>⊃</syntaxhighlight>) and [[Up Arrow]] (<syntaxhighlight lang=apl inline>↑</syntaxhighlight>).
