Finding the intersection of 2 short lines [message #79215]

Hi everyone.

I'm trying to find a way of detecting the crossing point of two short
lines (as part of a larger problem with detecting overlapping
polygons). I've used intersect.pro which gives me the general
intersect, but then I have to use the mother of all ugly if statements
(which I'm having trouble getting working) to detect whether the
intersect is actually on my short lines or extended away somewhere
else.

Is there a more elegant way of doing this? The code needs to find
whether the two lines cross, and return the intersection point.

Thanks all,
Jimmy
