[DUG] for..loop

[Robert martin]

Hi

Like others have said, it could change at any time.  If I need to nkow 
if something was found there is usually another variable asside from
the counter that can be checked. 

I almost always use while loops when searching for items as you can 
easily exit them without using 'Break'  (which I have an aversion to).  
I mainly use for loops for loading all values of a list.

p.s. has anyone else noticed that sometimes when you step through a for 
loop the counter actually counts down (in the debugger) (even if it set 
to count up).  This was the case sometimes in D6 if I recall correctly.
