BTW, you can just do "EXEC&H4000" (or EXEC16384 if you don't want to
deal with the & bit) - no need to mess with pokes or USR.
If the execution address is not present in the generated .bin file, it
means you have found a bug in the AS6809/ASLINK programs or you're doing
something that confuses them.
