Place all floats last without changing numbering

Question

I'd like to place some of my floats (specifically code listings) in my documents in a section at the end, without disturbing the numbering. Currently, I have them numbered within sections, so in section 1 all listings are called Program 1.1, Program 1.2 etc.

Is there a way to create a section at the end (like an appendix) where all the program floats go, without changing their numbering? Ideally, I'd like to have

Section 1
Some text in Section 1, and a reference to Program 1.1 and 1.2.

Section 2
Apparently Program 2.1 was the only code shown in this section.

...

Appendix A
Program 1.1:

for i = 1:n
    doStuff();
end

Program 1.2:

% This program doesn't do anything

Etc...

Update:
Before anyone shoots me for not showing exactly how the programs are defined, here's how it works:

% In the preamble
\usepackage{listings}
\usepackage{float}
\newfloat{program}{tbphH}{lop}
\floatname{program}{Program}

\newcommand{\codefrom}[2][Matlab]
{
\begin{program}[hbt]
    \lstinputlisting[language=#1]{#2}
    \caption{#2}
    \label{#2}
\end{program}
}

% In the document
\codefrom{alocalfile.m}

Answer 1

So this is my candidate solution which basically consists in manually moving all the floats to the end, and then temporarily hack into the section counter in order to show the desired numbers.

\documentclass{article}

\usepackage{float}
\newfloat{program}{tbphH}{lop}[section]
\floatname{program}{Program}

\newcounter{savesection}
\newenvironment{fromsection}[1]{%
  \setcounter{savesection}{\value{section}}%
  \setcounter{section}{#1}%
  \renewcommand{\thesection}{\arabic{section}}}
  {\setcounter{section}{\value{savesection}}}

\newcommand{\codefrom}[1]{%
\begin{program}[hbt]
    \caption{#1}
    \label{#1}
\end{program}}

\begin{document}

\section{Introduction}
Please see Program~\ref{dostuff} and \ref{donothing}.

\section{Another thing}
Also see Program~\ref{onlyone}.

\appendix
\section{Appendix}

\begin{fromsection}{1}
\codefrom{dostuff}
\codefrom{donothing}
\end{fromsection}

\begin{fromsection}{2}
\codefrom{onlyone}
\end{fromsection}

\section{Yet another appendix}

\end{document}

As the floats don't really need to “float” anymore, I would furthermore suggest to change their placement simply to “H” rather than “hbt”. Also I have no idea about the terrible things that this could cause if you're trying to use this together with hyperref.

Answer 2

Here's a bit of a hack that might be suitable for what you need. I hope you don't mind the floats appearing on their own pages. See the FAQ answer on floats for something of an explanation here. The code is uncommented but you should be able to get the gist of it. Also, be aware that you won't be able to have more than 36 floats using this technique.

\documentclass{article}
\usepackage{morefloats}
\usepackage{chngcntr}
\counterwithin{figure}{section}

\newcommand\allowfloats{%
    \renewcommand{\topfraction}{.85}
    \renewcommand{\bottomfraction}{.7}
    \renewcommand{\textfraction}{.15}
    \renewcommand{\floatpagefraction}{.66}
    \setcounter{topnumber}{0}
    \setcounter{bottomnumber}{0}
    \setcounter{totalnumber}{0}
}

\newcommand\dontallowfloats{%
    \renewcommand{\topfraction}{.01}
    \renewcommand{\bottomfraction}{.01}
    \renewcommand{\textfraction}{.99}
    \renewcommand{\floatpagefraction}{.99}
    \setcounter{topnumber}{9}
    \setcounter{bottomnumber}{9}
    \setcounter{totalnumber}{20}
}

\usepackage{lipsum}
\newcommand\textandfloat{%
  \lipsum[1-2]
  \par
  \begin{figure}[p]
    \centering\rule{5cm}{5cm}
    \caption{Black square.}
  \end{figure}
}

\begin{document}

\dontallowfloats
\section{Begin document}
\textandfloat\textandfloat
\textandfloat\textandfloat
\section{Middle}
\textandfloat\textandfloat
\textandfloat\textandfloat
\section{End document}
\textandfloat\textandfloat
\textandfloat\textandfloat

\allowfloats
\section{Floats}
Here are all the floats.

\end{document}

Juan A. Navarro, how can I modify your solution so that it works for figures, inclusive a List of Figures? I have tried the package endfloat for my figures but have encountered certain issues; that's why I am looking for an alternative way of putting all my figures in a separate Chapter in the end of my document but before the supplement.
