Causes <B>ftnchek</B> to report whether any subprograms
invoked by the program are never defined.
Ordinarily, if <B>ftnchek</B> is being run on a complete program, each
subprogram other than the intrinsic functions should be defined
somewhere.  Turn off this switch if you just want to
check a subset of files which form part of a larger complete program.
Subprogram arguments will still be
checked for correctness.  Default = yes.
<P>

The <B><A HREF="extern.html">-extern</A></B> flag is now superseded by the
<B><A HREF="usage.html">-usage</A>=ext-undefined</B> option.  For the sake of convenience, the
<B><A HREF="extern.html">-extern</A></B> flag is retained, so that <B>-noextern</B> is
equivalent to <B><A HREF="usage.html">-usage</A>=no-ext-undefined</B> option.  The
<B><A HREF="extern.html">-extern</A></B> switch may be retired eventually.
