<dd><p>The f90 command is an update to the original maxima fortran
command. The primary difference is the way long lines are broken.

<p>In the next example, notice how the fortran command breaks lines within symbols. The <code>f90</code>
command never breaks within a symbol.

<p>The <code>f90</code> implementation was done as a quick hack. It is not a
necessarily a good example upon which to base other language
translations.
</p>
<p>To use this function write first <code>load("f90")</code>.
