I'd be curious to see some of those assemblers. I've used dozens of
assemblers over the years for everything from microprocessors with a
few hundred bytes of memory to mini-computers and mainframes. I've
never seen one that didn't default to base 10 for integer literals.
I'm not saying they don't exist, just that it would be interesting to
see an example of one.
