pipe it into a data constant. That way it gets stored with the program
and can be used later.

yep- that would be slick. I've also long requested the ability
to determine whether or not the data on a given line/terminal is valid.
So perhaps a valid/invalid switch along with a "save" button
on the line probe.

If you compress a VEE program it gets a whole bunch smaller, so
you might ZIP it using max compression settings. Then mail it
or if it is really big post it somewhere for downloads.

As for the errors- you have a divide by zero somewhere- hence the overflow.

>From what I can see of your error messages the problem is inside
of your "regression" function. If this is a user object we need to
see what's inside it.

Otherwise, what is the full value of the inputs to the regression
object?

Also- it might make little sense to use a full regression routine
if you only have 2 data points. The regression/interpolation for
two points would be much simpler with a one-line formula ( think
2 pt form of a straight line ).
