It will probably return 0

Why don't you write a simple piece of code to test it yourself?

With #property strict, a fatal error "array out of range".

Without #property strict, 0 as mentioned by GumRai.

 I think that MT4 detects the invalid parameter and the function is not executed, so no fatal error.

Checked. You are right. Thank you.
