> For quite a long time I’ve being thinking if there could be a way of making usage of pointer a bit safer in Fortran. They offer many advantages but can be tricky if one is not careful about memory management. I have found very useful to define DTs with pointer components which can actually hold the data or simply point to external data and encapsulate processing procedures around the given DT. In order to have the flexibility of using the same DT as owner or pointer of the data I’ve used the fo…
