I believe the default is one-based. Whoever thought that one (or the whole feature of being able to set a start index for an array) up needs shot.

Default is 0. If you say something like "Dim Array(5) As Integer" then the indexes will be 0 through 4.

Yes the default base is 0, although the declaration in your example will actually have the indexes 0 thru 5. Lbound to UBound confirms this.

If you declare "Option Base 1", then the indexes will be 1 thru 5, so the only way (I know of) in VB6 to declare a variable to have 0 thru 4 indexes is "Dim Array(0 to 4) As Integer" which would also effectively ignore the set Option Base even if it was set to 1.

I stand corrected. Although there are a lot of websites out there that believe that arrays are defaulted to one-based.

Yeah, there's also a lot of places that think "Dim X, Y, Z As Integer" will create three Integer variables when it will actually create one Integer and two Variants. Another thing to watch out for.
