+{{Built-in|Execute|⍎}} is a [[primitive function]] that evaluates a [[string]] as APL code.
+It should be noted that executing user-provided data is not safe. Some implementations provide alternative safe functionality through the [[system function]]s [[Verify Input]] (<source lang=apl inline>⎕VI</source>) and [[Fix Input]] (<source lang=apl inline>⎕FI</source>)or the combined function [[Verify and Fix Input]] (<source lang=apl inline>⎕VFI</source>).

+A common use for this is to [[assignment|assign]] a value using a name given by a variable:
+<source lang=apl>
+      varName←'myVar'
+      myValue←42
+      {⍎varName,'←⍵'}myValue
+      varName
+myVar
