For all asynchronous RPC functions that your application uses, you will need to modify the declaration of the asynchronous functions within your application's ACF file. Apply the[async]attribute to each asynchronous function name, as shown in the following example: ...
There are a number of situations where subprograms (subroutines and functions) are of such a nature that the Fortran standard (and the compiler) requires that an explicit interface be provided in the caller. In such situations, the implicit interface (which could be called the F77 and earlier ...
