Example

Invocation

Here the shell is invoked three times from the command line. (The system command prompt is shown as $.) The first invocation executes a script specified on the command line itself. The next invocation has no arguments, so the shell goes into interactive mode, reading and evaluating each line as it is typed in. Finally, the last invocation executes a script from a file and accesses arguments to the script itself. -

spawn and sync

+	print("entry");
+	java.lang.Thread.sleep(x*1000);
+	print("exit");
+}
+js> var o = { f : sync(test) };
+js> spawn(function() {o.f(5);});

+entry
+js> spawn(function() {o.f(5);});
