Hello,
I am new to VBA, but I have been programming for many years. I am
trying to sort out the difference between a module, a worksheet, and a
workbook. In a single project, I can write code in a module, and/or a
worksheet, and/or a workbook. And if I write code in sheet 1, I can
use it to access all the other sheets in the project. So why is VBA
set up this way? What is the difference between a module, a sheet,
and a workbook? And how does it benefit me to have all these places
to write code, as opposed to just a single code location?

thanks for the help
Andrew
