% The task at hand is to increase \LaTeX's current limit of 18 unprocessed 
% floats in memory at once to 36. An examination of latex.tex reveals that
% this is accomplished by allocating an insert register for each unprocessed 
% float. A quick check of lplain.lis reveals that there is room, in fact, 
% for 230 additional unprocessed floats, but \TeX's main memory would be 
% exhausted long before that happened.
%
% First we allocate the additional insert registers needed:
%    \begin{macrocode}
\newinsert\bx@S
\newinsert\bx@T
\newinsert\bx@U
\newinsert\bx@V
\newinsert\bx@W
\newinsert\bx@X
\newinsert\bx@Y
\newinsert\bx@Z
\newinsert\bx@AA
\newinsert\bx@BB
\newinsert\bx@CC
\newinsert\bx@DD
\newinsert\bx@EE
\newinsert\bx@FF
\newinsert\bx@GG
\newinsert\bx@HH
\newinsert\bx@II
\newinsert\bx@JJ
%    \end{macrocode}
%
% That accomplished, the next step is to define the macro \verb+\@freelist+
% which is merely a list of the box registers each preceded by \verb+\@elt+.
% This approach allows processing of the list to be done far more efficiently.
% A similar approach is used by Mittelbach \& Sch\"opf's {\tt doc.sty} to
% keep track of control sequences which should not be indexed.
%    \begin{macrocode}
\gdef\@freelist{\@elt\bx@A\@elt\bx@B\@elt\bx@C\@elt\bx@D\@elt\bx@E
