Someone else must have mentioned 'C' along the way

No, you were the one!

You brought it up in saying that the SiLabs stuff is "C only".

since I'm not a 'C' afficionado.

Gosh - there's a surprise...!

;-)

I don't know what programming an MCU in HLL would have to do with converting code from 8035 (the romless 8048) which is apparently what the O/P has to deal with, and 8031 (the romless 8051) which is what he seems to want to use

Agreed.

                              read the Keil manual            01/01/70 00:00      
                           I don't believe that's the case            01/01/70 00:00
