Every native filesystem has got at least thirty character filenames. More
modern ones have bigger limits. Still, thirty characters is long to most, at
least until you start playing with MP3 files. =)
BTW, if you really want some multiuser stuff, there was a mufs update on
Aminet as late as yesterday. =)

It should be pointed out that AmigaDOS is just the DOS of AmigaOS. As we
established several months ago, AmigaDOS is very much a clone of the Tripos
system. And it was programmed in BCPL. Unlike the rest of the OS, which is
M68k assembler and C. Which caters for some funny acrobatics when the DOS
expects BCPL structures and the OS (as well as the programmer) would like C
structures. Originally, there was another DOS called CAOS under development.
It was more UNIX-like and more compatible with the OS, but since the
development dragged on, a quick port of Tripos was brought in as a
replacement. Frankly, I think it's for the better. As a non-programmer end-
user, it's really comfortable.

All this elaboration was just to ask: Was it really so fun programming for?

En ligne avec Thor 2.6a.
Amiga: (noun) The most technologically advanced computer that hardly anyone
cares about.
Use in sentence: "I wanted to buy an Amiga for its low price and great color
graphics, but everyone else seems to be using IBMs or Macintoshes. So, to
remain compatible with the rest of the world, I spent three times as much on a
Macintosh and got only half the graphics capability of an Amiga."
