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 functions Verify Input (⎕VI) and Fix Input (⎕FI)or the combined function Verify and Fix Input (⎕VFI).

Examples

      '⍳10'
1 2 3 4 5 6 7 8 9 10

A common use for this is to assign a value using a name given by a variable:

      varName'myVar'
      myValue42
      {varName,'←⍵'}myValue
      varName
myVar
      myVar
42
