<H1>How do I use <TT>pop_output</TT>?</H1>
<P>When you want to restore the previous output after using <A HREF=pushoutput.html><TT>push_output</TT></A>, simply
call the subroutine <TT>pop_output</TT>. If the output type
was a string, <TT>pop_output</TT> will return the string
(containing all of the output); otherwise, the return value is not
useful.</P>
<P>Usually, you will want to use <TT>push_output</TT> in
the start handler for an element or subdocument entity, and
<TT>pop_output</TT> in the end handler.</P>
