Glad to contribute. I thought there was something strange about a 2007 post being remarkably up to date.

I'll post what I got of the code for the G+, and the issues I found (so far) in it. Lbl lines need to be on their own line, or the G+ freaks out with Arg Error, i.e.

Code:

'Errors out with Arg Error with the cursor pointing to X
Lbl 0 X=R=>Goto 4

'No Error
Lbl 0
X=R=>Goto 4

The same can be said where Isz/Dsz lines get combined with their next lines, except this time it's a Syn Error

Code:

Lbl 1 Isz S
Lbl 2 Dsz Y Deg
...
' should read
Lbl 1
  Isz S
...
Lbl 2
  Dsz Y
  Deg
...

Once I cured these small errors, I was able to get the program to complete, with a time not much different from the other 9750G+ result (1m47.6s). I was really puzzled about the apparent addition of a do-nothing command Deg to the Dsz Z, but without it, the program doesn't work, because the statement Y=0=>Goto 0 is being treated as the "Z<>0" portion of the Dsz command instead of the "Z=0" and the Y=0 never gets evaluated. Things unwind when the List 1[X] - List 1[Y] happens, and you can't have List 1[0] on the G+. That caused me to hunt around for a good while trying to find the bug when I'd simply removed the Deg (as it looks like a typo).
