Thankyou for your kind response to my student Javaid Iqbal on errors in using floating point divide within IC software.

I'm still not sure what caused the problem, but a new bootstrap/reinstall of the pcode seems to have fixed the problem. I can now successfully use the printf function. Odd though, that that was the only command that wasn't working correctly. Todd (26 years ago, 21-Nov-98, to lugnet.robotics.handyboard)
