Absoft Fortran is designed to be fully compatible with the implementation of the Standard C Programming Language. The linker can be used freely to link C modules with Fortran main programs and vice versa.

However, some precautions must be taken to ensure proper interfacing. Data types in arguments and results must be equivalent. The case of global symbols in C is significant. The symbolic names of external procedure must match in case. More details...
