This is a loop statement. Further down in the code there should be "LOOP".
In the first line, it states to loop as long as the cell value is not blank.
The next couple of lines simply set variables. The variables set to cell
addresses.

Please does anybody knows what is this for? What is doing?

Do While ActiveCell.Value< ""
beginaddrs=ActiveCell.Address
endaddrs=ActiveCell.offset(0,35).Address
Application.ScreenUpdating=True

Thank you!!
