Sorry there is a small goof in my original code. Try this...

Sub ModifyOtherBook()
Dim wbkTarget As Workbook

On Error Resume Next
Set wbkTarget = Workbooks("That.xls")
On Error GoTo 0

If wbkTarget Is Nothing Then Set wbkTarget = Workbooks.Open("C:\That.xls")

wbkTarget.Sheets("Sheet1").Range("A1").Value = "Tada"
End Sub

Here is a very basic example. It modifies a workbook called That.xls. It
first checks if the book is open. if not it opens it. There is a workbook
object called wbkTarget that gives you a reference to the workbook we are
manipulating. The code is running in "ThisWorkbook".

Sub ModifyOtherBook()
Dim wbkTarget As Workbook

On Error Resume Next
Set wbkTarget = Workbooks("That.xls")
On Error GoTo 0

If wbkTarget Is Nothing Then Workbooks.Open ("C:\That.xls")

wbkTarget.Sheets("Sheet1").Range("A1").Value = "Tada"
End Sub

Hi Jim. Thank you for such a fast response. I want to be able to manipulate
a second workbook from a macro I start in the first workbook. It doesn't
matter where the execution ends.

Yes...ish but we need a little more clarification. Do you want to

1. manipulate another workbook
2. run code that exists in another workbook

Bare in mind the the thread of execution will always end in the workbook
that began the process, but that workbook does not need to be the active
workbook when the code ends.

Using Excel 2000 can you create a macro that works across more than one
workbook? For example, can a macro start running in one workbook and finish
in another? If so, is there any special code or actions you need to do to
make it work?

Thanks,
