--- Comment #13 from Andreas Heinisch <[email protected]> ---
After some investigation, here are my findings. Consider the following code
snippet:
Sub Main()
Dim strArray(2) As String
MsgBox LBound(strArray)
MsgBox UBound(strArray)
MsgBox UBound(strArray, 1) - LBound(strArray, 1) + 1
Redim strArray(3)
MsgBox LBound(strArray)
MsgBox UBound(strArray)
MsgBox UBound(strArray, 1) - LBound(strArray, 1) + 1
End Sub
Without any option:
- the array starts at 0 and ends at 2 with 3 elements.
- after the redim the array starts at 0 and ends at 3 with 4 elements.
With option base 1:
- the array starts at 1 and ends at 3 with 3 elements, since this option
increases also the upper bound (see #109275 in
https://jezzper.com/jezzper/discussions.nsf/0/3C030B7CC3F24D5FC1256F65002BC1B5)
- after the redim the array starts at 1 and ends at 4 with 4 elements.
With option base 1 and option compatible:
- the array starts at 1 and ends at 2 with 2 elements, since option
compatible does not change the upper bound
- after the redim the array starts at 1 and ends at 3 with 3 elements.
At the moment, the option base is not fully implemented and works only with the
additional VBASupport option.
