Also, the HP-15C has both one- and two-byte instructions so no lack of opcodes whatsoever, the number of possible opcodes vastly outnumbers the existing instructions by about two orders of magnitude.

thanks Valentin; shame they didn't add the 16C operations to the 15C, if they could have crammed in all the key-labels. Still, it gave me an excuse to order a 15L from Michael this week
