Thank you :-) The author, being born in 1987, while interested in how things came to be the way they are, only had an 8-bit and PCs, and needed to base it on some archive digging, and it was really satisfying. I have corrected the Fortran reference - was mislead by the "70", but it turns out it was more like a WIP standard that wasn't even in use until the end of the decade. Inserting on a DEC Writer must have been... not the most intuitive experience. I think inserting characters in the middle of the line wasn't practical on anything else than a screen, even if of an electronic typewriter? It's also a great point how case sensitivity may be confusing for beginners - it's the same word after all, isn't it?
