Is it possible to store a module (maybe export it and keep it in a specific
location), then 'call' it from the workbook. So it would be like having a
text file in a folder on your c drive and then instgructing the code to copy
the string and use it as a string variable in the code and run it from
within another sub.

e.g.

Sub GetOutsideCode

Dim sCode As String

sCode = TextFileInSpecifiedFolder.Contents

Call sCode

End sub


or some such thing. I know it used to be possible to get values from a
closed workbook using GetValue with excel 2003, don't know if it's still
available in 2007 (anyone know?) but it strikes me that if it is and my idea
above won't work, then storing the code in cells in a workbook should
produce the same end result.

One of my reasons for wanting to do this is that in order to protect
intellectual property in an excel workbook it could be possible to have the
file containing the code in the specified folder and then kill it at a
specified interval unless a passwrod was entered before that interval. Bit
of a whacky idea maybe but it should work well enough for the audience i
have in mind.

Thanks and regards, Mark
