How To Delete Multiple Workbooks Using Macro

[Launchnet]

Good Morning Everyone . . .
I am looking for a way to close a group on Workbooks that are in separate instances of Excel.

These Workbooks get opened similar to running a Powerpoint program, but much different usage than Powerpoint.

AS AN EXAMPLE:
I have 7 Workbooks open in Excel . . . Could be more or less.
Each workbook has 2 sheets, the "User Sheet" (not the actual name, as all user sheet names vary) and a sheet named "Setup." (Always named "Setup.")

On the "Setup" sheet I have a list of all the possible Workbooks that I want to close. For reference purposes only, I'll call this list "To Close". All 7 Workbooks would be listed, but not all of them would be opened. If any particular Workbook on the "To Close" list is not open, it would simply be bypassed.

Example of list: Column A

Row 25 has the name of Workbook A
Row 26 has the name of Workbook B
Row 27 has the name of Workbook C
And this would continue down to the last Workbook possibly open. I will know how many Workbooks could possibly be open.

Other workbooks could also be open, but they would not be closed by this macro. In this example, I would only want Workbooks A & B & C closed.

I would have rows 25 thru 27 (or more) listed in the same location on the "Setup" sheet of each Workbook.

Each "User Sheet" would have a macro called "Close Group"

The macro would have to search through all open Workbooks and when it found one of the Workbooks listed for closing, it would close that workbook. Then, the macro would look for the next Workbook on the "To Close" list.

The Active Workbook would also be on the list and that also needs to be closed. I would guess that this would be the last Workbook to close, but it really would not make any difference if the macro would still work. I think the macro has to have the active Workbook open to close the others.

After the list has been gone through, the macro would stop.

NOTE: Each Workbook has it's own "To Close" list. If it would help, I can leave the Workbook Name A off of the list in Workbook A. I would do the same on Workbook B, etc. Then the Active Workbook could automatically be closed at the end of the macro.

This is going to take someone many times more talented than me. I hope someone can help me.
