Dynamic calls are made in Fortran by specifying the name of the routine to be loaded with the DYNAMIC compiler option, and then using the same name in a CALL statement. The dynamically called routine can be either C++ or Fortran, and it can in turn statically call either a C++ or Fortran routine. (If the statically linked C++ routine is within a dynamically loaded module with a Fortran entry point, the C++ routine must be either nonreentrant or naturally reentrant.) In the dynamically loaded module, a routine can dynamically call other C++ or Fortran routines, regardless of whether the routines are reentrant.

Neither a C++ nor a Fortran routine can delete a dynamically loaded routine that was dynamically loaded in a Fortran routine.
