Alan, Your web page at http://www2.dynamite.com.au/aebrain/PROGRAM.HTM has some nice stuff. I appreciate your including my 1996 Team Ada posting on the comparison of C and Ada in my real-time embedded systems course. A more detailed version was published in CrossTalk and can be found at http://www.stsc.hill.af.mil/crosstalk/2000/aug/mccormick.asp And if anyone is interested in the current state of my model railroad lab, I have started a web site at http://www.cs.uni.edu/~mccormic/RealTime/ John ------------------------------------------------------- John W.
