<p>Comment (by Erik Schnetter):</p>
<p>A declaration <code>character*8</code> as input argument is really strange. one would only use that if one knows that the length is 8, similar to passing a character array in C (instead of a character pointer).</p>
<p>Usually one would write <code>character*(*)</code>, and the compiler then passes the actual string length as additional (hidden) argument, and uses that length in the callee.</p>
<p>In this case I rather think that the Fortran code is a mistranslation from C, and that the code generating the <code>_CHECKED</code> macro is wrong. <code>dtbetax_p</code> should be declared as <code>CCTK_REAL dtbetax_p(ash0, ash1, ash2)</code> instead. None of the Cactus grid function or parameter passing arguments or declaration use Fortran <code>character</code> variables.</p>
