I have a very large add-in that I build which is running very slow. In fact
it crashes excel if I run too many times. I am questioning the structure I
have used. I am wondering if the speed has something to do with either:
1) "Public Variables" or
2) the use of "Set" statement

I have been reading about memory leak in the new book by Bullen/Bovey/Green
(page 184) and their comments on memory reclaim. Not sure if it applies here
or not.

The routine effectively:
1) sets up 19 paste ranges, declares a public variable "Cell" and then loops
through every cell in the UsedRange of every sheet in the spreadsheet
(ListAuditResults Sub)
2) tests for 19 attributes (MainAudit Sub) - 1 at a time.
3) If the attribute is found (TRUE) then the routine pastes the cell address
of the variable "Cell" to a named paste range (CellAddressPass Sub) set up
earlier in the routine. This paste range increments on each successive
round. So effectively the routine checks every cell for attribute 1 and then
does it all over again for 2,3,4,5-19.

With regards to the memory leak issue, do I need to do something with the 19
paste range variables to reduce memory leak?

The code below is a rough representation of the routine. I have left out
many details as the does code works - its just slow. Note that I have only
provided details for Case 19 in the MainAudit Sub. All 19 have a Set
statement which increments the paste range for the attribute associated with
each Case.

Thanks in advance!
