<H1> H.1 Pragma Normalize_Scalars</H1>
<DIV Class="Paranum"><FONT SIZE=-2>1</FONT></DIV>
<DIV Class="Normal"> This pragma ensures that an otherwise uninitialized
scalar object is set to a predictable value, but out of range if possible.
</DIV>
<H4 ALIGN=CENTER>Syntax</H4>
<DIV Class="Paranum"><FONT SIZE=-2>2</FONT></DIV>
<DIV Class="SyntaxIndented" Style="margin-bottom: 0.2em">The form of
a <FONT FACE="Arial, Helvetica">pragma</FONT> Normalize_Scalars is as
follows: </DIV>
<DIV Class="Paranum"><FONT SIZE=-2>3</FONT></DIV>
<DIV Class="SyntaxIndented"> <B>pragma</B> <A NAME="I7000"></A>Normalize_Scalars;
</DIV>
<H4 ALIGN=CENTER>Post-Compilation Rules</H4>
<DIV Class="Paranum"><FONT SIZE=-2>4</FONT></DIV>
<DIV Class="Normal"> <A NAME="I7001"></A><A NAME="I7002"></A>Pragma
Normalize_Scalars is a configuration pragma. It applies to all <FONT FACE="Arial, Helvetica">compilation_unit</FONT>s
included in a partition. </DIV>
<H4 ALIGN=CENTER>Documentation Requirements</H4>
<DIV Class="Paranum"><FONT SIZE=-2>5</FONT></DIV>
<DIV Class="Normal"> If a <FONT FACE="Arial, Helvetica">pragma</FONT>
Normalize_Scalars applies, the implementation shall document the implicit
initial value for scalar subtypes, and shall identify each case in which
such a value is used and is not an invalid representation. </DIV>
<H4 ALIGN=CENTER>Implementation Advice</H4>
<DIV Class="Paranum"><FONT SIZE=-2>6</FONT></DIV>
<DIV Class="Normal"> Whenever possible, the implicit initial value
for a scalar subtype should be an invalid representation (see <A HREF="RM-13-9-1.html">13.9.1</A>).
</DIV>
<DIV Class="NotesHeader"><FONT SIZE=-1>NOTES</FONT></DIV>
<DIV Class="Paranum"><FONT SIZE=-2>7</FONT></DIV>
<DIV Class="Notes"><FONT SIZE=-1>2 The initialization requirement
applies to uninitialized scalar objects that are subcomponents of composite
objects, to allocated objects, and to stand-alone objects. It also applies
to scalar <B>out</B> parameters. Scalar subcomponents of composite <B>out</B>
parameters are initialized to the corresponding part of the actual, by
virtue of <A HREF="RM-6-4-1.html">6.4.1</A>.</FONT></DIV>
<DIV Class="Paranum"><FONT SIZE=-2>8</FONT></DIV>
<DIV Class="Notes"><FONT SIZE=-1>3 The initialization requirement
does not apply to a scalar for which pragma Import has been specified,
since initialization of an imported object is performed solely by the
foreign language environment (see <A HREF="RM-B-1.html">B.1</A>).</FONT></DIV>
<DIV Class="Paranum"><FONT SIZE=-2>9</FONT></DIV>
<DIV Class="Notes"><FONT SIZE=-1>4 The use of pragma Normalize_Scalars
in conjunction with Pragma Restrictions(No_Exceptions) may result in
erroneous execution (see <A HREF="RM-H-4.html">H.4</A>). </FONT></DIV>
