Please check your coding again, as errors do occur - see my previous post & the initial posting on this matter.

Gerald,
For the sake of completeness, I run your programs on my physical A and C machines.
I got:
version A machine: 414s
version C machine: 432s
consistent with the observation that version A is slightly faster (+5%).

I assume that there is something different in the implementation of your programs in your C machine.
Can you please check again? - Errors do occur :-)
Only you can do it since you are the only one to get such a speed difference (40%).

Please share your findings, I'm now curious...

Entered progs on the 2 machines are identical.

I am the only one to record a large difference in performance, but then the sample is very small.

I have frequently used the prog "FAST" on the version A machine, but these tests were carried out in the standard state, ie "FAST" was not operating.

Can repeated use of "FAST" have some permanent effect?

What are the serial numbers of your calculators?
