As I happened to be skimming through the User Guide in search of another answer I discovered this Caution (which may actually be a Warning) that scripts may fail silently if the Variable Watcher is open. It's on page 52 of the 6.6.1 GM version: ------------------------------ Variable Watcher: Opens the Variable Watcher window, which you use to keep track of the value of variables during debugging. When the debugger is not open, the variable watcher shows the value of global variables. Caution: Warning: this feature will cause your scripts to fail silently instead of giving an error message in the event LiveCode encounters an error. ------------------------------ So I just did a quick check, New Stack, added a button: on mouseUp breakpoint put 0 into x put 2 into y put y/x into z end mouseUp With Script Debug Mode turned On and the Variables window Open, when I step through the script and get to line 5, the Errors window is automatically bought forward with the following: button "Button": execution error at line 8 (Operators /: divide by zero), char 8 With Script Debug Mode turned Off and the Variables window Open, when I click the button I get the Errors dialog box pop up with: Type Operators /: divide by zero Object Button Line put y/x into z Hint mousUp I've raised Bug #12450 which is about errors in the User Guide as the Development Menu no longer has Variable Watcher as a menu item - so this is reference to earlier days when the Variable Watcher was a separate window (stack). The Bug Report also questions whether the Caution (or Warning?) is still valid. Was the problem solved when the Variable Watcher and Debugger where combined? If anyone does notice scripts failing silently it may be worth noting the combination of Script Debug Mode On or Off and which Tab (Errors, Variables, Documentation, Breakpoints, Search Results) was selected at the time and probably most importantly, what kind of error was being ignored. That could then be included with #12450. _______________________________________________ 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
