Handling Errors in an MDI Environment

By default, each document namespace is provided with its own *error* function, which is defined as follows:

(defun *error* (msg)

			 (princ "error: ")

			 (princ msg)

			 (princ)

)

A VLX application running within a document namespace shares the default error-handler function. You may want to add error-handling logic to your application.
