terminating a process in system exec via ctrl+c

[VEEDAY]

I am running a process in command window which is invoked by system exec. The only possible way to terminate and get back to the main command window is via Ctrl +c. How do I implement it?

ANy idea ...

I solved it... was quite easy.

Create a numeric constant corresponding to the ctrl-key, convert it as U8 and type cast and use the string output and paste in the command prompt. 

Works good ...
