Inverse Interpolation

I need to find the distance down a line.  Just wondering if there is a package (or anything really) that can perform Inverse Interpolation.

Cheers.

I know 2 points of a line.  Given a distance I need to find the point along the line and not the total distance.

I had to modify the code so it wouldn't draw, but otherwise everything was there.

Thanks.
