Returns a LONGCHAR value in either the code page specified in the HTML-CHARSET attribute, if that code page is valid for a LONGCHAR, or -cpinternal. Otherwise, it returns the Unknown value (?) and displays an error message. You can suppress this message by using NO-ERROR on the statement containing the method. This method is called by the get-cgi-long and get-long-value WebSpeed API functions. Intended for internal use only.
