I currently code mostly in C and C++. I still usually use the letters 'i' through 'n' to start integer variable names and the other letters for floating point variables. Funny how that works. Louis

It did have a C compiler whose principal merit was that porting to it was a thorough test of the quality of your code. Integers were 32 bits; pointers to integers were 32 bits; pointers to character arrays were 48 bits. There were quite a few eccentricities.

You know that Moor's law is about the number of transistors, not the speed of the clock, right? $.02 -Ron Shepard

Of course at that time "Real Programmers" usually meant Fortran Programmers, but it was a more general description of old style programmers. In this context Fortran means the "proper" tools for these guys, who also "don't write comments. The code was hard to write, it should be hard to understand."
