Filling message boxs with lists? How to?

Hi there, ive set up a little program that basically gives out a list of numbers derived from a sieve, so 3 to the base 2 gives me 2, 5, 8, 11, 14, 17, 20, 23 and so on.

I then use the zl group object to make sets of how ever long I want so say 'zl group 4' will output 2 lists from the above numbers in the max window when I use the print command so the first list/set would be 2, 5, 8, 11 then 14, 17, 20, 23.

My question is how would I get those numbers into each of there own separate message boxes? So that when the zl group outputs its first group of numbers it fills one message box, then when it outputs the other list it fills another box.

So in the end I have this program that basically can create different size lists/sets of numbers from sieves and have those sets automatically stored in message boxes in the max window to be used later.

One reason why I would like this is so I can then get my groups that are in the messages box and perform unions and intersections with these boxes, with other message boxes containing other lists/sets from another different sieve, say 4 base 3 or something.

Also, I cannot find a way to get a group of numbers coming from the zl group object to become an index in the coll object, so I am hoping that being able to put them into message boxes first will help me to put them into coll.

Thanks for you time!

Mark.
