These changes facilitate more robust parameter type checking and helps to identify unexpected coding errors. Most simulators can now also be compiled with a C++ compiler without warnings. Additionally, these changes have also been configured to facilitate easier backporting of simulator and device simulation modules to run under the simh v3.9+ SCP framework.
