</span>Hi Yingchao,<br>
<br>
You solution is a good one. It should not cause any problems with either<br>
the current or near-future versions of the code.<br>
<br>
The header file "FortranLangFeatures.fh" (included already in releases<br>
since FLASH 4.2 or so) is used to enable or disable use of a couple of<br>
compiler features that were introduced officially in Fortran 2003 or 2008,<br>
but are also implemented by many compilers that don't fully support those<br>
standards. These features, including using INTENT(OUT) on POINTER variable<br>
declaration, can help a compiler in making optimization decisions, and can<br>
help eliminate code errors. None of them are needed for code correctness.<br>
<br>
If you can come up with a preprocessor test for detecting your compiler<br>
that has problems with "POINTER,INTENT(OUT)", along the lines of the tests<br>
already in Simulation/<wbr>FortranLangFeatures.fh, you should add it there;<br>
and I would appreciate a copy so we can make it available in the next code<br>
release!<br>
