This table lists each subprogram followed by a list of the routines it calls. This switch is equivalent to <B><A HREF="calltree.html">-calltree</A>=reference</B>. Default = no. <P> The reference list omits routines called by unused library modules. Thus it contains the same information as for the call-tree format, namely the hierarchy of subprogram calls, but printed in a different way. This prints out a breadth-first traversal of the call tree whereas <B><A HREF="calltree.html">-calltree</A>=tree</B> prints out a depth-first traversal. <P> See also: <B><A HREF="calltree.html">-calltree</A></B>, <B><A HREF="crossref.html">-crossref</A></B>, <B><A HREF="library.html">-library</A></B>, <B><A HREF="sort.html">-sort</A></B>, <B><A HREF="symtab.html">-symtab</A></B>, <B><A HREF="vcg.html">-vcg</A></B>. </DL> <P> <P><HR><P>Next: <A HREF="resources.html">-resources</A> </BODY></HTML>
