Re: Find the rightmost character ('/') on an address link

[Peter_Vidal@xxxxxxxx]

Hey Scott, thanks for that good tip!  Yes, I used some recommendations but I am
also new to procedures so I will try this one too.

Thanks!

I realize that you've already solved this...  (it's a pretty common
thing to need to do, so I imagine many people have or will give you
solutions)

But, here's a slightly more efficient method.  Rather than scanning the
string several times to find all the slashes, it uses the C "strrchr"
function which scans for a single character, starting at the end of
the string...   since it only scans the string once, it'll run slightly
faster...

     D my_file         S             50A
     D my_path         S            256A
