Apl Functional Symbol Zilde Symbol Meaning

⍬ is the APL functional symbol zilde (Unicode U+236C). In APL, it represents an empty array—an array value with no elements. The practical takeaway is that it can be used anywhere you need “nothing there” as a value, rather than omitting a result. Depending on context, operations involving zilde help produce empty results safely and consistently. Because it’s a symbol rather than plain text, it’s often copied into documentation, code comments, or UI labels that refer to APL behavior. The symbol’s Unicode name is “APL FUNCTIONAL SYMBOL ZILDE”.
