I agree, strings would be useful for all sorts of things and Forth style strings would work better than zero-terminated. Ironically, the C folks who bashed Forth strings back in the day, now have new "safe" library calls using the same counted string mechanism to avoid stack buffer overflow attacks. :) The main reason not to add strings is AFAIK HAL doesn't currently work gracefully with items that are not basically atomic in nature. This is in the process of changing with the zeromq and queuing changes Michael's working on, but it's a bit much for me to want to tackle just to release an easier-to-understand pin numbering scheme. -- Charles Steinkuehler char...@steinkuehler.net
