Yes. You can do this. Using multipart arrays is probably better than my usual technique of simply building an ordered index separately, and possibly adding it to the array (if I need to pass the data around a lot) - under some safe named key like "_SortedIndex". I guess you have the same problem when you want to generate indexes from the keys - you'd have to extract the second column from the keys - I have to delete the line "_SortedIndex"... so yes it is doable and not really "hard". So I think we are on the same wave length. We differ in that I'm complaining about it :) For beginners - it is counter intuitive (I remember having to ask on list about it when learning - and takes up space explaining in the documentation). It takes a lot of lines of code, and messes up otherwise nice clean data structures with hacks just to get around the fact that you don't key your keys back in the order you put it in, and it is a very common task. I want my arrays to look like; put firstTitle into tArray["title"] put secondTitle into tArray["title"] put fourthTitle into tArray["title"] put thirdTitle into tArray["title"] and not put firstTitle into tArray[1,"title"] put secondTitle into tArray[2,"title"] put fourthTitle into tArray[4,"title"] put thirdTitle into tArray[3,"title"] whereever possible :) Multidimesnsional arrays do my head in. Why would anyone want the reverse? Just to change the subject - how about making it easier to create text string containing quotes - that's my number 1 grumble regarding elegant, easy to write code. Having to hack arrays to get indexes back in the order i put them in in only number 2. _______________________________________________ use-revolution mailing list [email protected] Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
