<A HREF="http://rredc.nrel.gov/solar/codesandalgorithms/spa/">http://rredc.nrel.gov/solar/codesandalgorithms/spa/</A> , output,to a
stepper motor control program driving motors x,y respectively.

which could a read "spa",in this instance every twenty seconds, and
write to a stepper program. suspect the solution would include time.h.
Anyone able to point me in the direction? Best Regards, Anthony K
