<H4 ALIGN=CENTER>Legality Rules</H4>
<DIV Class="Paranum"><FONT SIZE=-2>3</FONT></DIV>
<DIV Class="Normal"> The renamed entity shall be a generic unit of
the corresponding kind. </DIV>
<H4 ALIGN=CENTER>Static Semantics</H4>
<DIV Class="Paranum"><FONT SIZE=-2>4</FONT></DIV>
<DIV Class="Normal"> A <FONT FACE="Arial, Helvetica">generic_renaming_declaration</FONT>
declares a new view [of the renamed generic unit]. </DIV>
<DIV Class="NotesHeader"><FONT SIZE=-1>NOTES</FONT></DIV>
<DIV Class="Paranum"><FONT SIZE=-2>5</FONT></DIV>
<DIV Class="Notes"><FONT SIZE=-1>15 Although the properties
of the new view are the same as those of the renamed view, the place
where the <FONT FACE="Arial, Helvetica">generic_renaming_declaration</FONT>
occurs may affect the legality of subsequent renamings and instantiations
that denote the <FONT FACE="Arial, Helvetica">generic_renaming_declaration</FONT>,
in particular if the renamed generic unit is a library unit (see <A HREF="AA-10-1-1.html">10.1.1</A>).
</FONT></DIV>
<H4 ALIGN=CENTER>Examples</H4>
<DIV Class="Paranum"><FONT SIZE=-2>6</FONT></DIV>
<DIV Class="Normal" Style="margin-bottom: 0.4em"> <I>Example of renaming
a generic unit:</I> </DIV>
<DIV Class="Paranum"><FONT SIZE=-2>7</FONT></DIV>
<DIV Class="Examples"><TT><B>generic package</B> Enum_IO <B>renames</B> Ada.Text_IO.Enumeration_IO; <I>-- see <A HREF="AA-A-10-10.html">A.10.10</A></I></TT></DIV>
<H4 ALIGN=CENTER>Extensions to Ada 83</H4>
<DIV Class="Paranum"><FONT SIZE=-2>7.a</FONT></DIV>
<DIV Class="Annotations"><FONT SIZE=-1><A NAME="I3430"></A>Renaming of
generic units is new to Ada 95. It is particularly important for renaming
child library units that are generic units. For example, it might be
used to rename Numerics.Generic_Elementary_Functions as simply Generic_Elementary_Functions,
to match the name for the corresponding Ada-83-based package. </FONT></DIV>
<H4 ALIGN=CENTER>Wording Changes from Ada 83</H4>
<DIV Class="Paranum"><FONT SIZE=-2>7.b</FONT></DIV>
<DIV Class="Annotations"><FONT SIZE=-1>The information in RM83-8.6, ``The
Package Standard,'' has been updated for the child unit feature, and
moved to <A HREF="AA-A.html">Annex A</A>, except for the definition of
``predefined type,'' which has been moved to <A HREF="AA-3-2-1.html">3.2.1</A>.
