I did remember the include file (note lack of 'implicit declaration'
warning).

I am using 2.01; I will download the new version later (when all the new
Christmas users have finished playing :-/ ). Exception support is a
great bonus (my code is much neater and less error-prone due to using
try{} and catch(){} constructs) - although, as you say, it won't 'cross
the link' between DXE and EXE. This isn't a problem due to the way DXEs
are used; if the DXE falls over, the EXE is going to fall over anyway - 
who cares that I can only return a char *?

I don't suppose that ctors/dtors in global objects work in 2.02?

Well, thanks for taking some time to explain this to me. Bye for now,
