program to program communication

[elfanddot]

Thank you even if you can't answer!
Does anyone know of or explain a method of either communicating between two program (one main, one child)
in a dos environment.
I need to either start a program from within another program with some starting arguments and ignore the program, or i need to constantly pass information between the two. the first method is prefered because the starting arguments are ment to be the address of a class where the main program can change value and the child program can read the values. although any working method to get me going will work fine.
