I am using the Cells object to set the "locked" property of
my spreadsheet. The line looks like this:

Cells.locked = True ' or can be False

I feel real uncomfortable using that code by itself. Shouldn't
I pre-qualify the Cells object with another object such as
"ThisWorkbook" or something?? I just want to ensure that
this code runs on the workbook it was intended for and not
another active workbook.

Thank you!
