There is a reason Richard Gaskin was promoted to LC ombudsman.
This is as useful and powerful as the "messageMessage".

Right now "the result" sometimes contains data, but sometimes contains error info. The "it" variable also sometimes contains data, but (almost?) never contains error info. Sometimes errors put error info in "the result", and other times they explicitly throw an error, requiring the use of try/catch in those cases but not others. That's a whole lotta "sometimes". We have a function for system errors in sysError, but that only applies to things happening outside of LC (file I/O, processes, etc.). Wouldn't life be much easier if we had one reliable way to obtain info whenever an error occurs in our scripts? Maybe simply: get scriptError() ? Ideally this could be handled like the changes to "word" and "char", in which new tokens are rolled out while still maintaining the older way also for several versions, so we have plenty of time to update code at our leisure, using the simpler method going forward while the old code continues to work. And given that Open Language is just around the corner, wouldn't it seem this is the best moment to clean up the mish-mash of inconsistent error handling we have to deal with now? -- Richard Gaskin Fourth World Systems Software Design and Development for the Desktop, Mobile, and the Web ____________________________________________________________________ ambassa...@fourthworld.com http://www.FourthWorld.com _______________________________________________ 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
