I have 2 programs. One is a test case generator(A) and the other is the program (B) the test cases refer to. Now, I was told to use some sort of system command to call B and input arguments as generated from A. Then, A is supposed to generate a .dat file of time-to-errors to be used with CASRE. The problem is that I cannot find any such system call and how to use it. Does anyone have a suggestion on where to look? Thanks :)
