That is excellent. Thank you! Your concise example is very fine. It's short and sweet and it runs as is on NetBSD (where I'm browsing from). Thanks very much indeed.

It's late tonight, but I'm copying it to flash memory for adapting to my Win32 program on the laptop tomorrow. Come Monday I'll try it out on the machine in question.

FYI -- My particular stepper motor application is to dial up a 20-turn needle valve in a test rig cycling pressure (ramp up, hold, ramp down) thousands of times on a jet engine fuel nozzle. Have to do it that way because this is for a contamination test. The fluid in question is JP-8 jet fuel loaded with calibrated dirt (hematite, rust, Arizona road dirt and lint) and no proportinal or servo-valve would last even 10% of the test.
