Re: Looping Over Groups?
Thanks Ken, that's perfect. It's not quite the behavior I'd expect being used to other languages (I thought by referencing my group in the repeat structure it would implicitly reference elements in that group during iteration), but I think I'm finally getting into the spirit of this language. :-) At 10:59 PM 9/23/2002 -0500, Ken Ray wrote: Jim, Try this for your second line: answer the name of image i in group players_group The problem is that the number of the images change when you add an image to the card.

Hi folks, I've run into an additional problem here, and I hope you can help . . . I've created a group of 14 images. As advised, I loop over them like so: repeat with i = 1 to the number of images in group players_group answer the name of image i end repeat Works great. When I click on the Object -- Edit Group menu, all 14 show up as expected. However, when I add another image to the card (but not to the group) and run the same code, the new image is included in the loop (even though it's NOT in the group), and the last image in the group is not (even though it should be). When I click on the Object -- Edit Group command my original 14 images are there and the new image is not, which is what I'd expect. It's the looping behavior that is not what I'd expect. It seems (just guessing though) to be pulling the image at positions 1 through 14 regardless of whether or not they are in the group. Am I doing something wrong, or is there another approach I should be taking? Thanks!

I think people have been so enthusiastic about advising the efficient repeat for each form that the other forms have gotten a little eclipsed. ;-) The repeat for each form can be used to iterate over chunks in a string - characters, words, lines, items - or over each element in an array, but it can't be used to iterate over objects. The first and third variations you tried wouldn't compile because repeat for each image and repeat for each object aren't valid forms of the repeat loop. The second one, repeat for each item, is valid... but in this context, an item is a part of a string, not an object, so this doesn't work either. And the fourth, while a valid form, requires an array, not a group reference. Here's a form that will work: repeat with x = 1 to the number of images in group my_group answer the name of image x -- or whatever end repeat -- Jeanne A. E.

Re: Looping Over Groups?
Jim, Try this for your second line: answer the name of image i in group players_group The problem is that the number of the images change when you add an image to the card.
