Hi Kay,
so I can avoid the 'goshhhh, now I need to change all those to .......... because I need to.....' moments ;-)
One reason to avoid globals... suppose you have a working app that is (just for example) a calendar. It can create and save a calendar as a document (data file). You use a global 'gSaveFlag' whose value is 'true' when the user changes the calendar. You know to save the changes when 'gSaveFlag' is true. Someday you decide to rewrite your app so that it can open two calendars at once. You may find the globals in one calendar are cross-reacting with the globals in the other calendar. If you use a substack as a calendar viewer/editor, and set the saveFlag of substack 'myCalendarViewer' to true, you can then clone the substack as many times as you like and each clone will have its own 'saveFlag'. hth, Michael Binder _______________________________________________ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
