Hi again,
as an addendum to the initial post, I've mad the following modifications and
htey appear to be working, with the exception of one element that I can
identify thus far.
This macro looks in the directory A, compares to directory B files, and
either gives a message box stating it's already been processed, or starts
following through to process.
The last element opens a workbook, calls to a SaveNewFormat macro which then
processes the workbook, saves it as a read only, and then closes it. Once
that is complete, it jumps back to this macro, to look for the next file to
compare, and determine if it needs to be processed or not. If process is yes,
it opens another workbook, but for some reason not yet understood, it either
opens a secondary workbook, or leaves the first book open.... we're still not
clear on this yet.
If I understand it correctly, FNum does not advance, or if it does advance,
it then resets by looping twice through the FNum routine, below.
'----------------------
For Fnum = LBound(MyFiles) To UBound(MyFiles)
Set myBook = Nothing
On Error Resume Next
Set myBook = Workbooks.Open(myPath & MyFiles(Fnum))
On Error GoTo 0
Next Fnum
'--------------------
as stated, I'm not clear here on why it'd peform this twice. But it appears
to do just that. I think it's part of the FNum resetting itself to 1, from
some higher numeric value.
Your input is greatly appreciated.
Best.

the file name for the first file.
