Expand description

Get an element from a list by index

Stack effect: ( Variant Int – Value Bool )

Returns the value at the given index and true, or a placeholder value and false if index is out of bounds.

§Error Handling

  • Empty stack: Sets runtime error, returns 0 and false
  • Type mismatch: Sets runtime error, returns 0 and false
  • Out of bounds: Returns 0 and false (no error set, this is expected)

§Safety

Stack must have an Int on top and a Variant (list) below
