-_key_ is an optional variable standing for array's index (from 0 to LEN(_array_) - 1) or MAP's key. _key_ type is INTEGER for arrays and [[STRING|eberon-strings]] for [[MAP|eberon-associative-arrays]]s.
+_key_ is an optional variable standing for array/string's index (from 0 to LEN(_array_) - 1) or MAP's key. _key_ type is INTEGER for arrays and strings and [[STRING|eberon-strings]] for [[MAP|eberon-associative-arrays]]s.
 _value_ is a variable standing for element's value.
 These variables have no a separate declaration and their visibility scope is inside loop only. Also these variables are read-only - similar to non-VAR parameters.
