U+233B "⌻" Apl Functional Symbol Quad Jot Unicode Character

Unicode Version 17.0

U+233B "⌻" Apl Functional Symbol Quad Jot is a graphic symbol from the APL programming language, representing the quad jot operator, which is rarely used in modern APL but historically denoted a function that combines the "quad" (a symbol for I/O or the identity function) with the "jot" (the comma operator or outer product indicator). Specifically, in APL notation, this symbol could serve to indicate a modified outer product operation or a specialized call to a system function, though its exact semantic meaning varied across implementations and dialects, often intended for advanced array manipulation or system interaction. As part of the APL character repertoire, it is encoded in Unicode to preserve the full set of vintage keyboard symbols used in the early development of array-oriented computing.
