Hi

I'm writing a macro that I wish to go row by row through the worksheet until
it get to the end and then stops. It is a bit complex, so I won't try and
explain what I'm doing, but I've got about 30 workbooks with a few thousand
rows each.

Any suggestions on how to stop at the end if I use a similar way of moving
around as the following example (this example is moving by column, whereas
I'll want to work on each row then move down a row, moving by row.)

Selection.End(xlDown).Select
ActiveCell.Offset(0, 1).Select
ActiveCell.FormulaR1C1 = "=RC[-1]*100"
Range("D2").Select
ActiveCell.FormulaR1C1 = "=RC[-1]*100"
Selection.Copy
Range(Selection, Selection.End(xlDown)).Select

Many thanks for your help.
