if I am understanding your question correctly than you want it to where in the command prompt you can type :

program.exe /a 2 2

where program.exe uses a as a parameter to add the two numbers

this may not be what your program does but I'm using this as an example. If this is what you would like to do then you are in luck because it is absolutely EASY!!!!
