How can this func return 1?

[MHz]

Definitely a bug.  Test this small script for proof:

MsgBox(4096, "", Test1()); Prints 500

Func Test1()
    Test2(); No Return statement!
EndFunc

Func Test2()
    Return 500
EndFunc

<{POST_SNAPBACK}>

I do not get post #5. The result of Test1(), in the messagebox is the result of Test2(). If you do not want this reponse, do not call Test2() from Test1(). This is logical.

Does anyone have a better example.

MHz, it shouldn't return anything... it wants the return from Test1, which is nothing. Not the return from Test2.

Get it?

No, if Test1(), does not return 500, then that would be a bug.

; Example from Valik.

MsgBox(4096, "", Test1()); Prints 500

Func Test1()
    Test2(); No Return statement!
EndFunc

Func Test2()
    Return 500
EndFunc


; Same as

MsgBox(4096, "", Test1()); Prints 500

Func Test1()
    Return 500;; Replaced function call with function code.
EndFunc

...I don't believe it works like that in PHP/C++?

Let me test it in PHP...

<?php
    echo Test1();
    
    function Test1()
    {
        Test2();
     }

    function Test2()
    {
        return 500;
    }
?>

Doesn't return a thing.

Why? Because I don't tell it to, I tell another function to return something. If functions started doing things you didn't tell them to, that'd be kinda buggy wouldn't it?

EDIT:

Not trying to be a dick, it's just not supposed to work that way.

Don't think so... Valiks example should return a 0 since you would expect an implicit "return 0" when in func test1 like:

MsgBox(4096, "", Test1()); Prints 500

Func Test1()
    Test2(); No Return statement!
    Return 0  
EndFunc

Func Test2()
    Return 500
EndFunc

This is what the helpfile says about it:

Use the Return keyword to exit the function. Unlike built-in functions, user-defined functions return 0 unless another return value is specified.

Even this returns 500:

MsgBox(4096, "", Test1()); Prints 500

Func Test1()
    Test2(); No Return statement!
    Return  
EndFunc

Func Test2()
    Return 500
EndFunc
