If file is present, it specifies a file where the help information is stored. If the file name ends in the four characters ".hlp", it is a windows help file. If the file name begins with the five characters "http:", it is a complete world wide web address. If the file name begins with the "\" character, or if its second character is the colon character ":", it is a complete path specification. Otherwise the file name is relative to the O-Matrix installation directory.
When file is present, topic specifies the help topic within the file (for HTML files this is the NAME field corresponding to an anchor within the file). If topic is an empty matrix , no topic is specified within the file.
Leading and trailing white space in topic and file are ignored.
