 Cody fixed an infinite loop where the program would print the same thing over
 and over again, flooding the screen. The problem is that there was a `for` loop
 that by necessity had to not have an increment stage but only in the `if` path
-(in the loop itself) did the pointer get updated. Looking at the code it might

 Cody also provided an [alternate version](1989/ovdluhe/ovdluhe.alt.c) based on the
