chapter31

There are a couple of nice statements you can use to control processing within loops, namely

• break
• continue

Break is of course used to exit the current loop entirely and resume page processing from the first CF statement after the end loop tag. Lovely!

Continue has a subtle but handy difference, it ends the current loop iteration and ‘continues’ from the beginning of the next loop iteration. Very lovely

Now the problem is that there is no ColdFusion tag equivalent for continue, it’s only accessible when in a <cfscript> block. As far as I know this is the only statement in the CFML language which is available in <cfscript> but not tags

For some scenarios this will be ok, especially for the cfscripters out there. But for people who don’t like (for several reasons) <cfscript> then this is a limitation which I hope Adobe will address (among others!) in Scorpio.

And don’t forget that the inherent limitations of <cfscript> (limited cftag support) means that sometimes you won’t be able to do your logic in cfscript. For example you may want to use a <cfsavecontent> etc which you can’t do in <cfscript>.

I know…I know that you can create your own functions simulating tag functionality in cfscript but all gets a little messy doesn’t it?
