yes, that is exactly what i was thinking of... i just could not find any sample 
code in my library... as noted, i have used it and it sounds similar to what the 
OP is looking to do... one thing i used to use it for was counting the number of 
time that a routine was called during the course of execution... other times i 
used it were in relation to recursion IIRC...

NOTE: i've never done this with strings but i would guess it would work, too...
