|

|
|
|
|
<P>The standard binary output format generated by the linker for the
|
|
Atari target is a machine language program with a standard executable
|
|
header (FF FF <2 byte start address> <2 bytes end address>
|
|
[program bytes]). These values are calculated in the crt0.s
|
|
file from the __CODE_LOAD__ and __BSS_LOAD__ values, so keep this in
|
|
mind if you create a custom linker config file and start moving
|
|
segments around (see section
|
|
<A HREF="atari-8.html#memhole">Reserving a memory area inside the program</A>). You can
|
|
override this behaviour by creating your own crt0.s file and linking
|
|
it into your program. A run vector is added to the end of the file
|
|
($02E0 <run vector>) and is calculated using
|
|
__CODE_LOAD__ in crt0.s.</P>
