Rob – we just all need to go back to Lotus 123, where the offsets for the Index and Lookup functions are zero based

Declaring lower and upper bounds is a matter of personal choice. While it is more natural to you, it would be unnatural to me. In fact, it would upset me to find it.
I think it was a good design choice to force zero-based arrays in .NET. The consistency brings it's own benefits.

While I'm here on my box, I also think Excel should also introduce row zero. *ducks*

Michael,
I think Tushar's last note was in reference to some compiled languages such as VB.NET, which does not allow you to explicitely declare a lower bound - it must be zero. I also don't understand why they added this "feature" to VB.NET, and it still causes me a few problems when I try to translate code from VBA to VB.NET.

Hi Tushar -

Not sure I follow your last note. You can Dim array bounds to suit. From the Help for LBound and UBound, for example:

Dim A(1 To 100, 0 To 3, -3 To 4)

UBound(A, 1) = 100
UBound(A, 2) = 3
UBound(A, 3) = 4

LBound(A, 1) = 1
LBound(A, 2) = 0
LBound(A, 3) = -3

Hi Tushar,

And since LBF + LBT are both constants within the loop you could have declared one variable LBFPlusLBT and compute that before the loop starts.
