Nah, we all make such mistakes when we start. In fact, I still occasionally forget to align the odd variable here and there.

Probably Ross used that designation to match the symbols from amiga.lib with the same name. Alternatively you could import these symbols from amiga.lib with
xref _LVODisable
, etc., without having to know their exact value.

Especially if you want to write to them, or take their address with '#', right?
These are the cases where the assembler has to add a relocation entry to your executable. The format of that relocation table is
HUNK_RELOC32SHORT
by default (to save some space), which AmigaDOS only understands since OS2.0. Hence,
-kick1hunks
, which you should always use when targetting Kickstart 1.x systems.

Now, that certainly explains why it refused to run with 121. Thanks for the explanation.
