<h3>Controlling Variable Scope in for Statements</h3>
<p>If you enable the Legacy for-scoping setting , the compiler generates an error when it encounters a variable scope issue that the ISO C++ standard disallows, but is allowed in the C++ language specified in <strong>The Annotated C++ Reference Manual</strong>.</p>
<p>With this option off, the compiler allows variables defined in a for statement to have scope outside the for statement.</p>
<div class="listing">
<h4>Listing 1. Example of a Local Variable Outside a for Statement</h4>
<p>for(int i=1; i<1000; i++) { /* ... */ }<br />
return i; // OK in ARM, Error in Carbide.c++</p>
</div>
<p>This setting corresponds to the pragma <a href="../pragmas/p_arm_conform.htm">ARM_conform</a>. To check this setting, use <span class="code">__option (ARM_conform)</span>. By default, this setting is <span class="code">off</span>.</p>
