APL Quad Up Arrow

⍐ is an upward arrow inside a rectangular frame, belonging to the symbols of the APL programming language. The frame is called a “quad.” Although it looks like a direction sign, its documented use is a file operation, not an instruction to move upward.

What ⍐ means

It is an APL programming symbol for working with files.

APL is a programming language that uses mathematical-looking symbols to express operations on data. The arrow and its surrounding frame form one character: the box is part of the notation, not a decorative border.

In the early-1970s Burroughs APL/700 system, ⍐ meant “take”: select a portion from the beginning or end of a file. Files were treated as ordered lists of components, each holding a value or collection of values. This is a historical use, not a universal command shared by all APL systems.
