Hi
Like others have said, it could change at any time. If I need to know
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.

Why does the Delphi help say that a For loop variable has an undefined
value
after the loop finishes it's iterations? Surely the variable is always
1
greater than the maximum "To" value. That is what appears to happen in
all
situations I've tested. I often use this test after a For loop to tell
if
something was not found. What would cause a different result than this?
Cheers,
Ross.
