[Pdx-pm] string function

I'm having trouble thinking of a good way to compare two strings and 
find out where they differ.

For example, given:


I would like to find the number of matching characters starting from 
the front or back of the strings. These would be,

	3 match from the front
	4 match from the back

There must be some slick way to do this without looking at each 
individual character in a loop. What am I missing?

Thanks -- Ward
