 '''The modified user-interface files cannot be pre-compiled by using mbuild! '''\\\\
 While programming user-defined code, errors are frequently made. For possible ways of error tracing see [../../intdbg Debugging]. 
+
+In case you are calling MPI functions or external functions from your user code, you might get error messages during the namelist file check, which is performed before your job is started. These errors will not occur during your model run, so you might skip the parameter file check in this case. The better option, however, is to exclude these calls from this check. In order to achieve this, can set the preprocessor directive {{{__check}}} whereever needed. 
+
+'''Example:'''
+{{{
+#if ! defined ( __check )
+CALL MPI_ALLREDUCE(...)
+#endif
+}}}
