Re: Index of current iteration in for-each loop

Hi all

Thank you for all your clarifications. I'm now using the

for i = 1 to %elem(Elements)

construction. I still think updating the current element via a named index would be great so I added an Idea

Err, this would run a WHOLE LOT faster than having to do a %LOOKUP on
each element:

for i = 1 to %elem(array);

item = array(i);

endfor;

Not only faster, but more understandable too.

You could also do this:

i = 0;
for-each item in array;
i += 1;
...
endfor;

But I think using the FOR loop is better because it keeps everything
inside the loop.
