I will be grateful for any advices re the following. I have read similar but
the file names are hard coded. I have a list of files to open using a macro
and to work on so file names are held in a variable as opposed to being hard
coded into the macro.

How do i check to see if a file is already open, the name is say held in
cell A10 on sheet 1 for example and the next to open will be say A11 and so
on.
