I thought the recursion limit was 40,000, not 400,000.

So it can be more than 65535 so long as you do not try to set it separately. I know from experience, when I created an app that maxed out the default 400000 due to too much recursion, that setting it higher (20000000 in my case) actually did do something. The app worked fine after that. I’m going to submit a bug report and see what happens (if anything). _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
