SYNOPSIS
        mixed * get_error_file(string name, int set_forget_flag)

DESCRIPTION
        Return information about the last error which occurred for
        <name> (where <name> is a valid name from the wiz list).

        Result is an array of four elements: the filename of the
        program where the error occurred, the linenumber in the
        program, the error message (runtime error messages usually
        start with a '*'), and a numerical flag (the 'forget flag') if
        the error information has been queried already.

        If there is no error stored for the given <name>, 0 is
        returned.

        If <set_forget_flag> is non-zero, the 'forget' flag is set
        for the error message after it has been returned.
