> My recollection is that most CP/M programs were configured via patching. At least that’s how I configured them. I remember my WordStar manual coming with details about which bytes to patch to do what. There was also a few dozen bytes of patch space set aside for you to write your own subroutines, in case you needed to add custom support for your printer.

Huh. That is interesting, it was before my time, and I never heard of this :D

I didn't know it was such a chaos.

So I guess the moral of the story is: Ensure they always point to the same path, or else...

1995-ish. Telstra (Australia Telecom). Probably about 50k desktop computers across the organisation. One day a small file turned up in everyone's network home directory called null. A *nix person had evidently had a go at writing a .bat file.

Why do we need to adopt extant standards? (I was going to ask, why standardise? But realised that might confound the North Americans. : )

I assume that they first tried /dev/null which failed, so then moved onto just plain null?

Otherwise it would not make sense, unless they misspelled NUL as null.
