<p>Comment (by Roland Haas):</p>
<p>SYNC is definitely not case sensitive. In the same schedule.ccl file there is:</p>
<div class="codehilite"><pre><span></span> SYNC: Scalar
</pre></div>
<p>which compiles and works fine.</p>
<p>Note that the reason why schedule groups are case sensitive is very different from the one why scheduled routines written in C are. The latter are case sensitive since the linker symbol that is the C function preserves the case that is used in the C source code (which is not the case for Fortran scheduled function which are not case sensitive). Thus you get a link time error if you provide the wrong case for a C scheduled routine.ON the other hand, schedule group names never show up as a C identifier anywhere and are case sensitive because the flesh’s C code (in <code>CCTKi_DoScheduleFunction</code>) uses <code>Util_GetHandle</code> to get the group handle, which function uses <code>strcmp</code> on the handle name, which is the scheduled group name as it appears in schedule.ccl.</p>
<p>If there was a problem making <code>READ</code> / <code>WRITE</code> case insenstitive then that problem should be fixed.One problem that comes to mind would be generating variable names in <code>DECLARE_CCTK_ARGUMENTS_Checked</code> if one used the <code>READ</code> / <code>WRITE</code> strings in a case sensitive comparison against the full list that is currently used.</p>
