Poor Behavious of UBound Function

Reported by: nitrogen Owned by:

Version: Severity: None

Description

For UBound function, it gives me an impression that it should return the UPPER BOUNDARY of an array, but it actually returns the SIZE of array instead.

For example, we loop an array using this

Dim $myArray[10]
For $r = 0 to UBound($myArray) - 1

$myArray[$r]=$r

Next

But if ubound really return the upper boundary, it should be

Dim $myArray[10]
For $r = 0 to UBound($myArray)

$myArray[$r]=$r

Next

In VB, UBound does return the upper boundary but NOT the size of array.

Thanks!

The behavior of VB is stupid.

Even I hate VB, I think VB behaves more logically correct.

UBound should return the Upper Index of an array instead of Upper Index + 1,

If you name UBound as ArraySize, then the current implementation is correct.

I am interested to see other admin's comment

Actually, you're just plain wrong. Visual Basic and VBS both behave very much like AutoIt.

If you need to track the last used index then track it yourself. AutoIt cannot do that for you. No language can do it with 100% reliability to suit everyone. AutoIt, VB and VBS all have the correct behavior which is to report what the highest possible index is (keeping in mind the index needs offset by subtracting 1).
