Interesting if useless discovery - LC accepts real numbers as Point
values,
ie "22.5,31.7", not just integers. I haven't discovered if it rounds
or
truncates them in use though.

Walt,
A caution.
LC accepts real numbers as the Loc of objects but integers only as the
points of line graphics.
If you say:
set the points of grc 1 to 100,100 & cr & 200,200.5
the graphic disappears. Worse yet, you get no error message. This
becomes a problem when your points are calculated and the calculation
yields a fraction somewhere without you realizing it.
However if you say:
set the loc of grc 1 to 150,150.7
there is no problem. The 150.7 is truncated to 150.
I have asked RunRev (many years ago) to change this anomalous behavior
but without success.
Jim
