EXTRACT <br> Painless Module Extraction
</h1>
<hr>
<p>
<b>EXTRACT</b>
is a FORTRAN90 program which
pulls a copy of a FORTRAN
block data, function, module, program or subroutine from a big file,
and saves the copy in a little file.
</p>
<p>
I've found <b>EXTRACT</b> extremely useful,
as an alternative to printing out a huge library of routines, or using
an editor to extract the seven routines I need from a collection of 200.
</p>
<h3 align = "center">
Usage:
</h3>
<p>
<blockquote>
<b>extract</b> <i>module</i> <i>file.f</i>
</blockquote>
where
<ul>
<li>
<i>module</i> is the name of the desired module;
</li>
<li>
<i>file.f</i> is the file to be searched.
</li>
</ul>
If the module is found, it is written to a file named <i>module.f</i>.

Related Data and Programs:
</h3>
<p>
<a href = "../../cpp_src/catalog/catalog.html">
CATALOG</a>,
a C++ program which
reads a C, C++, FORTRAN77 or FORTRAN90 program and prints every line
that begins with a special index tag. If the program has been marked
up expecting this convention, it is a handy way of making a table
of contents of a program file.
</p>
<p>
<a href = "../../f_src/f77_cleanup/f77_cleanup.html">
F77_CLEANUP</a>,
a FORTRAN90 program which
makes a copy of a FORTRAN77 file in which some minor cleanups have
been made.
</p>
<p>
<a href = "../../f_src/fixcon/fixcon.html">
FIXCON</a>,
a FORTRAN90 program which
reads a FORTRAN file using FORTRAN77 continuation statements,
and makes a copy that uses FORTRAN90 continuation instead.
</p>
<p>
<a href = "../../f_src/f90split/f90split.html">
F90SPLIT</a>,
a FORTRAN90 program which
reads a FORTRAN file and creates individual files for every
subroutine or function in the file.
</p>
<p>
<a href = "../../cpp_src/htmlindex/htmlindex.html">
HTMLINDEX</a>,
a C++ program which
reads a FORTRAN program and writes a skeleton HTML page describing it,
assuming that each subroutine includes a '!!' or 'cc' description line.
</p>
<p>
<a href = "../../f_src/include_files/include_files.html">
INCLUDE_FILES</a>,
a FORTRAN90 program which
reads a FORTRAN program with INCLUDE statements, and makes a copy
with the indicated files included.
</p>
<p>
<a href = "../../f_src/module_mark/module_mark.html">
MODULE_MARK</a>,
a FORTRAN90 program which
replaces bare "END" statements by "END (module name)" statements
in a FORTRAN90 file.
</p>
<h3 align = "center">
Source Code:
</h3>
<p>
<ul>
<li>
<a href = "extract.f90">extract.f90</a>, the source code;
</li>
<li>
<a href = "extract.sh">extract.sh</a>,
BASH commands to compile and load the source code;
</li>
</ul>
</p>
<h3 align = "center">
Examples and Tests:
</h3>
<p>
<ul>
<li>
<a href = "extract_prb.f90">extract_prb.f90</a>,
a sample text file from which modules are to be extracted;
</li>
<li>
<a href = "extract_prb.sh">extract_prb.sh</a>,
a BASH script which invokes EXTRACT several times, to extract
modules from EXTRACT_PRB.F90. The script also prints out
the modules to show what has been retrieved.
</li>
<li>
<a href = "extract_prb_output.txt">extract_prb_output.txt</a>,
the output file;
</li>
</ul>

<ul>
<li>
<b>MAIN</b> is the main program for EXTRACT.
</li>
<li>
<b>CH_CAP</b> capitalizes a single character.
</li>
<li>
<b>DIGIT_TO_CH</b> returns the character representation of a decimal digit.
</li>
<li>
<b>FILE_EXT</b> determines the "extension" of a file name.
</li>
<li>
<b>GET_UNIT</b> returns a free FORTRAN unit number.
</li>
<li>
<b>MODULE_FIND</b> searches a file for the first line of a given module.
</li>
<li>
<b>MODULE_WRITE</b> writes out the lines of a file until 'END' is reached.
</li>
