Static Check for Interface Parameters Unlike function modules, when a method is called the system performs a static syntax check on declared interface parameters. This applies to both local and global classes. It checks that the declared formal parameters are valid, the actual parameters have the correct type, and that all the obligatory input parameters have had values passed to them.

Cause:

Reduces runtime errors when the program runs. The extended program check performed on interfaces s not always sufficient.
