The user is first given the chance to provide the file name, which should begin with ``drcerror.log'' to be recognized as a DRC errors file for subsequent reading into Xic. After the file is created, the user is given the option to view the file in a File Browser window. If no file name is given, the file will be written to a temporary file which is erased on program exit. This may be convenient if the user only wants a quick view of the text.
Tha Update Highlighting command button provides the reverse operation, recreating the highlighting from an existing error log file.
