An assortment of instructions have been implemented so far, mostly basic
stuff such as stack management. The following program can be executed:
int main(void)
{
hello(2);
for (;;) {
system.Peek();
system.Sleep(1);
}
return 0;
}
void hello(int n)
{
int i;
for (i = 0; i < n; i++) {
system.Output("Hello, world! " + string(i));
}
}
