I'm trying to get my head around a 10-bit machine optimised for C... Well, if you accept that chars are 10 bits wide then there shouldn't be (much of) a problem; just forget about the concept of powers of 2, I guess. Shades of the 60-bit CDC series, as handling strings was a bit of a bugger; at least the 12-bit PDP-8 was sort of manageable. -- Dave --1483753691-1814802814-1612323130=:70858--
