In Part 16, we saw a demonstration of Apple Logo, a computer programming language promoted as an alternative to BASIC. This next episode of The Computer Chronicles features another version of Logo–this one developed and sold by co-host Gary Kildall’s Digital Research–as well as a broader discussion of the state of computer programming languages around early 1984. The other languages presented in this episode–COBOL, Forth, and Pascal–are still in use today, even if they are not necessarily at the top of the Stack Overflow survey of most popular programming languages.
