The Amiga's multitasking OS is based on the Tripos operating system which
was developed here in Cambridge. Tripos was implemented in BCPL (also
developed here :-), so much of the original Amiga OS was also written in
BCPL (especially dos.library and many c: commands). All of the BCPL code
was replaced with C code in v2.0x of AmigaDOS, but for compatibility
reasons, calls to dos.library still involve BCPL-style pointers, which are
different to C pointers. Strings are handled differently by BCPL too.
