Keywords
ERRMSG    = If defined and passed, then any error messages will be
            returned to the user in this parameter rather than
            depending on the MESSAGE routine in IDL.  If no errors are
            encountered, then a null string is returned.  In order to
            use this feature, ERRMSG must be defined first, e.g.
                ERRMSG = ''
                FXBCLOSE, ERRMSG=ERRMSG, ...
                IF ERRMSG NE '' THEN ...
Calls
None.
Common
Uses common block FXBINTABLE--see "fxbintable.pro" for more
information.
Restrictions
The file must have been opened with FXBOPEN.
Side effects
