That reminds me - one of the great secrets of computing
appears to be a three-way diff, as exemplified by diff3.

It is packaged in things like CVS/git, so people are
potentially using it by accident, but I'm not sure what
the situation is.

I still use CVS and I do the 3-way diffing across an
entire source base. I only know very simple git so I
don't use it there.

But absolutely I need to go back to 1987 or thereabouts
and get a simple demo of diff3.

I didn't pick it up (by osmosis) until 1995 or so, I think.

However - diff3 and patch can be written in pure C90 -
that's how I was able to get them working on MVS.

Regarding the OSes and CPUs - absolutely - if you write
your tools in a standard language (I know C90 works,
but I'm not sure what else is available that is portable),
then you shouldn't need to know or care what OS or CPU
you are on.

And you only have to go back to 1990 for that. Or 1989
in fact. It was already there. Perhaps it was more of a
question of saying "use it - what's wrong with it?"?

BFN. Paul.
