@node Offset
@section @code{.offset @var{loc}}
@cindex @code{offset} directive
Set the location counter to @var{loc} in the absolute section. @var{loc} must
be an absolute expression. This directive may be useful for defining
symbols with absolute values. Do not confuse it with the @code{.org}
directive.
@node Org
@section @code{.org @var{new-lc} , @var{fill}}
