It's the way index-based loops work. At the first pass of the <cfloop>, the INDEX variable is created with the initial value, and the condition (in this case the condition is an implicit "index variable value <= TO value"). If the condition is true, the loop block is entered. At the bottom of the loop block, execution is returned to the top of the block, the index variable is incremented by the STEP value (the default being 1), then the condition is evaluated again. If the condition is met, we're back into the loop block; if not, processing skips down to the first statement after the <cfloop /> block.
If you desk-check this, you will see that on the last iteration of the loop, the index value will be incremented beyond the bounds of the TO value, making the loop exit. So its final value will always - intrinsically - be higher than the TO value, by the amount of the STEP value. It's just how these things work. -- Adam On 1 March 2013 00:46, funand learning <funandlrnn...@gmail.com> wrote: > > I am sorry, I wasn't clear. the "to" is arraylen.
