The operating system was single-tasking; only one program could run at a time. There were no modern features like protected and mapped memory. Even so, it was possible to create concurrent behavior in programs, but you had to be careful to keep any part from blocking execution. For example, there could be no loops waiting for keyboard input or very long processes. Writing a non-blocking program was tricky in languages like Clipper.</p>
