and tried running Han's Graph3D app, but it has a problem setting the ranges
for the x,y, and z axes. It rejects negative numbers-I get an Invalid Input
error. I can work around this problem by eliminating the single quotes and
entering the negative number directly. There is probably a simple fix for
this in the software.

Sorry I didn't respond to this post earlier (was away during the summer, so to speak).

Depending on which version you used, 6030 does break the app. Version 2.2 (with rotation) relied on TRIANGLE, which was updated in 6030. As for getting invalid input for your ranges, it may likely be due to your fraction mark setting. I use decimal, and many folks who ran into errors similar to yours were those who changed their fraction marks to commas. Then, of course, there is RPN mode which hasn't been tested.

Anyway, I placed an updated version that pretty much combined all the nice features of all prior versions. So now you can get smooth 3D rotations as well as trace features and translucency. If you prefer having opaque graphs with proper "hidden-line-removal" then simply change the transmode:=1 line to transmode:=0 in the source code (pretty much first non-comment line in the code).

Thank you Han for the updated version. It runs significantly faster on my Prime than the older version when rotating the plot. My original complaint, however, is still there-a minor one but it is likely easily corrected:
When I enter a negative value for the lower limit of either X,y, or z in the range settings, I get an 'Invalid input' error. When I try entering it a second time, it accepts it without error. I don't mind this minor inconvenience but I thought I would call it to your attention anyway.
