Aargh, not allowed to edit my post....
Regarding the DIV32 - I was wrong, it's more the other way around. Doing Dummy = 1000*1000 won't work because both are constants. At least one of the vaules must be a variable or the compiler will replace the multiplication with a constant resulting in the internal system variables not containing the value for DIV32 to operate on. See here and here for more details.

Sorry for the mixup in my previous reply.
