<p><a name="index-_0040code_007bglobal_007d-directive-335"></a><a name="index-symbol_002c-making-visible-to-linker-336"></a><code>.global</code> makes the symbol visible to <code>ld</code>. If you define
<var>symbol</var> in your partial program, its value is made available to
other partial programs that are linked with it. Otherwise,
<var>symbol</var> takes its attributes from a symbol of the same name
from another file linked into the same program.
<p>Both spellings (<span class="samp">.globl</span> and <span class="samp">.global</span>) are accepted, for
compatibility with other assemblers.
<p>On the HPPA, <code>.global</code> is not always enough to make it accessible to other
partial programs. You may need the HPPA-only <code>.EXPORT</code> directive as well.
