Pointer Declaration

Include POINTER attribute. For example:

real, pointer :: PtoR,  PtoR2

PtoR, PtoR2 are pointers to a scalar, REAL target.

real, dimension(:,:), pointer :: PtoA

PtoA is pointer to a rank 2, REAL array of REALs.

Note that

• the declaration fixes the type, kind and rank of any possible target;
• pointers to arrays are declared using deffered-shape specification;
• rank of the target is fixed, but actual shape may vary;

POINTER attribute is incompatible with ALLOCATABLE or PARAMETER.
