I would like to know if there are any documentary stories about Forth's application for Industrial controls, such as to open/close control valves and other actuators based on input data from sensors, in real-time for process control. Comparision of C versus Forth for above types of applications. Since Forth is it's own operating system, how does it compare with other commercial real-time operating systems. Any comments and pointers to sources relevant to computerised process control will be greatly appreciated, since this is part of my Master's degree in EE thesis. Lastly, what would be a good chip, DSP's compared to '386 or others in general for these applications. Thanks and Regards, Raju

I am not sure why, but it seems that every person I've talked to who claimed he was a Forth programmer seemed to be romantically involved with the language. I don't think I ever got an objective opinion from a Forth programmer-- they all insisted, with gleaming eyes that, "Forth can do *anything*!!!!!" All sarcasm aside, the feel that I got was that Forth was good for a small, embedded application. If you are involved in a project that will have many communicating modules, though, Forth may not be appropriate, because of its explicit stack-based parameter passing. This can produce errors that are hard to detect. I'm sure there is a member of the Forth Cult out there who will insist that Forth is great for everything, but I remain unconvinced. >Raju - Eugene Walden (walden@dip.eecs.umich.edu)

I believe he may have a comparison of Forth and LynxOS - realtime Unix. You can reach him at uunet!lynx!vik Nathan Banks
