+\section{Termination Check Injection}
+
+Due to the non-preemptive nature of the virtual machine, the termination\footnote{Default key combination: Shift+Ctrl+T+R} signal must be explicitly captured by the app, and taking care of it by yourself can be extremely tedious. Fortunately \thedos\ parses the user-written program and injects those checks accordingly.

+While- and For-loops are always have such checks injected, but the `read()` is not checked for the termination.
