Why 'Row' changes to 'row' in Excel VBA

Question

For unknow reason my Excel VBA editor changes:
Cells(ActiveCell.Row, 1).Value = MyString
into
Cells(ActiveCell.row, 1).Value = MyString

Answer 1

I used variable row in VBA of that worksheet. Then I changed the name of the variable row to something else like MyRowName Although there was no such variable as row in VBA anymore, it still kept lower case for that word. As I mentioned above everything worked fine i.e. ActiveCell.row returned what it should for ActiveCell.Row.

For just aesthetic reasons, I have copied the whole VBA to another worksheet and the bug was crunched. Row returned to Upper case.
