Well, never done anything of the sort, but here are some ideas. For the zoom option map the best way would be to use a big image and resize it as you use the zoom in-out tool, but that way maybe the image is too big and the app would slow down a lot because of the big image. If this happens i guess your best shot would be to use different images for different degrees of zooming, and you should be careful enough to register these variations between maps so you can then adjust your coordinates for object displaying and placing (example: if you use a 100% and a 50% map, then in the 50% map you should display your objects at object.size/2) for making n-markers (if i understand quite right what youre trying to do) your best possibility is to use lists (marker=[m1,m2,m3...]) if youre not familiar with lists check the lingo dictionary, is quite simple (again, i donīt know if i understood right what youīre trying to do, i guess itīs that you have one set of variables and you want to use many sets and not just one, then lists is the way to go) Diego Landro ----- Original Message ----- From: "sasa" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Sunday, November 30, 2003 8:50 AM Subject: <lingo-l> Any idea?
