{{Built-in| | {{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]] (<syntaxhighlight lang=apl inline>⎕VI</syntaxhighlight>) and [[Fix Input]] (<syntaxhighlight lang=apl inline>⎕FI</syntaxhighlight>)or the combined function [[Verify and Fix Input]] (<syntaxhighlight lang=apl inline>⎕VFI</syntaxhighlight>). | |||
== Examples == | == Examples == | ||
< | <syntaxhighlight lang=apl> | ||
⍎'⍳10' | ⍎'⍳10' | ||
1 2 3 4 5 6 7 8 9 10 | 1 2 3 4 5 6 7 8 9 10 | ||
</ | </syntaxhighlight> | ||
A common use for this is to [[assignment|assign]] a value using a name given by a variable: | |||
<syntaxhighlight lang=apl> | |||
varName←'myVar' | |||
myValue←42 | |||
{⍎varName,'←⍵'}myValue | |||
varName | |||
myVar | |||
myVar | |||
42 | |||
</syntaxhighlight> | |||
