<DD>Specifies
that a who-calls-who table be printed. 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. <blockquote></DD>
</DL>
<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>
