So in this case it's not the expression "arrayLen(someArray)" that's passed into the tag's code, it's the value of "arrayLen(someArray)", for example "2". So the TO value is immutable once it's first evaluated. A conditional loop is different, in that the string that is the condition is passed into the code, not the result of it at the time the tag is called, eg: It's "someVar LE 3" that's passed to , not the result of "someVar LE 3" (which would be TRUE initially). -- Adam ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:354749 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm

The index variable is * specifically* there to be used. Using an additional counter variable is just tautology. You say "if it isn't documented...", but it is. Clearly so: http://help.adobe.com/en_US/ColdFusion/10.0/CFMLRef/WSc3ff6d0ea77859461172e0811cbec22c24-71aa.html I would potentially agree that using it outside the loop (ie: after the end of it), might not be a good idea, because some languages only maintain the index variable within the loop code. That said, CFML is not one of those languages. -- Adam ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:354748 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
Re: question on cfloop
It's the way index-based loops work. At the first pass of the , 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 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 wrote: > > I am sorry, I wasn't clear. the "to" is arraylen.

Re: question on cfloop
Not sure, but I believe the index at loop completion is incremented - that's
how it knows how to stop. So it's similar to
j=1;
while(j<2) {
j++;
}
I've never used the loop index, and I don't think you should depend on it. Not
sure what documented behavior is, but if it isn't documented in a specific way,
it would be totally appropriate for it to go out of scope in a future version
(kinda surprised it doesn't)
Instead, use your own counter var.
