 use AIMAG.  IMPORTANT: Do not use REAL or CMPLX without KIND=dp, or else you 
 will lose precision (except when you take the real part of a 
 double precision complex number).
+\item Do not use automatic arrays (e.g. \texttt{REAL(DP) :: A(N}} 
+in a subroutine) except if you are sure that the array is small in all
+cases: you may easily exceed the stack size if the arrays are large.
+\item Do not use pointers unless you have a good reason to: 
+allocatable arrays should be used instead.
+\item If you use pointers, nullify them before performing tests on their
+status.
+\item Do not pass unallocated arrays ar arguments, even in those cases where
+they are not actually used inside the subroutine.
+\item Do not use any construct that is susceptible to be flagged as 
+out-of-bounds error, even if no actual out-of-bound error takes place.
