IIUC there was nothing wrong with the OP's example. But how is the compiler supposed to know the difference? Either it always warns, and generate false positives when you compile the user of a variable before loading the defvar, or never warns and there are false negatives when the user makes a typo. In this case, false positives are the better option, since you can easily silence them by adding a defvar. If the warning were removed, there's no way to get the warning when you actually do make a typo. -- Barry Margolin, barmar@alum.mit.edu Arlington, MA *** PLEASE post questions in newsgroups, not directly to me ***
