I've put it all in a module so I'll export zip
and send it.

Can you send an email adress to shove it to please?

And you don't have to find out about unused by running  your own code.
There's a great set of VBA tools called MZ-Tools of which V3 is free.

And... IMHO.. Modyfying code  isn't such a big deal really. I know of some
programs for example that have a fixed data area.. ( another reason to put
data in one place maybe ) and to swap languages a block of memory is swapped
in.

Actually there is an issue with modifying VBA code but I'll tell yer when I
send the code. The most tricky thing I've tried to date is to define
vartiables "on the fly". I had a list of variables that I kept adding to and
didn't want to keep updating the code so I got the code to write a small
procedure that updated the dims and initialised the variable in situ so to
speak. It worked but I wasn't 100% happy with it.

I's like a lot of stuff I guess... If you know what you're doing then
anything can happen in the next half hour...
