AMIGA alive "Quick Clips"

"Quick clips" are a number of quickly recorded and little edited videos of what you might call "everyday Amiga issues" - installing a software package, fixing some C code, transcoding a file from one format to another, and the likes.

So far, these "quick clips" can be found on the YouTube channel:

A little odd: TAG_DONE and TAG_END

Sometimes one might get confused when to use TAG_DONE in AmigaOS C-code, and when to use TAG_END. The answer is very simple: They're one and the same. But it turns out there might be a little bit of an unknown story to these two widely used tokens.

TAG_DONE showed up before TAG_END, in NDK1.3, along with struct
TagItem, but not as part of the system includes, and the TagItem system
wasn't used in system functions.

Or was it? This is a section of code from the file Read-Me1.3/A2024Docs/OpenA2024.c, which is part of NDK1.3.
