Or C :(
I use the manufacturer C code generated by their tool as reference. In 
C, initializing a structure element with an address is not a problem.

I can redefine the records with UInt32 instead of System.Address. The 
problem is : What is the expression to convert from Address to UInt32 
without using a function ?
