Finding in reverse

[Robert Sneidar]

Is there a way to scan a text string from end to beginning for  
something without using a loop? I am trying to "be binary" (for those  
of you conference goers) and I am trying to extract just a file's  
name from the full path. It seems to be something of a difficult  
thing to do in a one liner.

What would have helped is if the offset function had some way to  
reverse directions, like an arguement that made offset work end to  
beginning. Foxpro has 2 functions that are similar, AT() and RAT().  
The R is for reverse obviously, and the number is for occurances not  
characters to skip. Oh well. Maybe we need an roffset() function. :-)
