Hey, I don't know if this is possible but lets say i made a macro called "test" and exported the .bas file to C:\
is there a way to make a new macro that would call to C:\test.bas and run the code in it?
No. Not practically. Most people keep such functions in Personal.xls. Two other options available are storing your code in any workbook and then setting a reference to it from the workbook that will be utilizing the stored code. Similiar in function, compile your code into a dll.
What are you trying to do? Why do you feel the need to store your code elsewhere?
