<dt><em>Description</em>:<dd>Frees memory previously allocated by <code>MALLOC</code>. The <code>FREE</code>
intrinsic is an extension intended to be used with Cray pointers, and is
provided in GNU Fortran to allow user to compile legacy code. For
new code using Fortran 95 pointers, the memory de-allocation intrinsic is
<code>DEALLOCATE</code>.
<br><dt><em>Standard</em>:<dd>GNU extension
<br><dt><em>Class</em>:<dd>Subroutine
<br><dt><em>Syntax</em>:<dd><code>CALL FREE(PTR)</code>
<br><dt><em>Arguments</em>:<dd>
<p><table summary=""><tr align="left"><td valign="top" width="15%"><var>PTR</var> </td><td valign="top" width="70%">The type shall be <code>INTEGER</code>. It represents the
location of the memory that should be de-allocated.
