I need to know it there is any realistic way, the operative word here is
realistic, to have vast tracts of VB code exist and be usable independent of
a set of worksheets.

The application is only 4 or so sheets but the volume of code supporting the
application is quite large. Unfortunately in the MS world, elegance is
expensive. The problem being that the entire .xls file is unacceptably large
and not only saves at glacial speeds, it seems to have grown to the point
where Excel's reach exceeds its grasp and is somewhat delicate. Saving the
file while doing development is unpredictable and often entertaining.

Using a personal.xls file will keep the code separate and get it to load but
actually using it is painful. The 'Application.Run' method is unacceptable.
Not only is is exceedingly clumsy, you cannot use named parameters.

Is there any way to tell Excel where to look to resolve procedure
references? Or am I simply SOL?
