What is the correct way to trim off the the first 37 characters of a  
string?

I want to trim off the value from position 0 -\> pos 37 or take off all  
characters from right side and stopping at a specific character #.

myval = wererwerwerwerweritop123233434345556#personID

How is this done? Thanks.  
MC

Take your pick!
