It also states in the Euphoria performance docs to save values where you can
I did a test of length( ) and found that if I got the length of a sequence
OUTSIDE the loop first that this was the faster method...

Subject: loops & perfomace
Hi,
i've got an performace question. We've got a loop
for i=1 to length(s) do
...
end for
is length(s) evaluated every time loop is done? So would be in Euphoria
faster
l= length(s)
for i=1 to l do
...
end for
as i read in one C book?
