The OS_Exit in the header is I think a 'Belt & Braces' - ie not usually
used.

Have you tried downloading the demo of 'DeskDebug' - there is a nice
program of a Multi-tasking game in Assembler.
If you are using a 26bit RO then '!Arm_Debug' (ask for latest) and
course there is '!Reporter' - they may be of some use.
Have a look at a !Runimage file (in '!Zap') - which was created by the
'C' compiler - its of course be ARM code now - it will show the AIF
header.
Drucks - '!ARMalyser' program is pretty good at disassembly - try your
programs in it.
