Some strange stuff with local vars.

[Andre' B]

Plotting this program it seems to think variable #32 is always zero.
If I replace the three uses of #32 with #27, thru #31 it works the same way.
But if I replace them with #26 or #25 it works as expected.
I did not check all the numbers less then #27 but I expect they would also work.
Variable #99 does not work but #100 does so I expect any global would work but only locals less then #27 would work.


I have not tried running on a actual machine yet either.

Andre',

I tried your program, but I am not seeing what you describe. Do you get the same results when you plot it from the variable display window?

Yep get the same results.

Here are some screen shots of using variable #32, the rough and both finish passes stop at the end of the 0.25 radius.

And the second that works the way I think it should when using #26, the rough and first finish pass stop 0.010 out from the end of the 0.25 radius and the second finish pass goes out 2.000 from the end of the radius.

Upload is not working, will try later.

Andre',

After looking at this some more, I've managed to find the problem. NCPlot handles the G70 cycle as a subprogram and must pass the local variables to it. However, only the first 26 variables are being passed.

Thanks,
Scott
