The glyph up arrow (or pike, in A Dictionary of APL) is an upwards pointing arrow represented by the Unicode character ↑, "upwards arrow". The up arrow has several uses in various dialects:
- In all dialects, <source lang=apl inline>↑</syntaxhighlight> is Take when used dyadically (except very early versions of APL\360, which used it for Rotate).
- In SHARP APL, <source lang=apl inline>↑</syntaxhighlight> is Nub when monadic.
- In APL2, NARS2000, GNU APL, and APLX, <source lang=apl inline>↑</syntaxhighlight> is First when monadic.
- In Dyalog APL, dzaima/APL, and ngn/apl, <source lang=apl inline>↑</syntaxhighlight> is Mix when monadic.
- In A+, <source lang=apl inline>↑</syntaxhighlight> is Signal, giving an error with the specified message, when monadic.
