[comp.sys.atari.st] Executables

rjwalsh@unix2.tcd.ie (Robert Walsh) (02/20/91)

	I have noticed at the beginning of an executable program file that there is a branch into the main program, followed by a
few numbers, followed by the main object file. What are these numbers? I have used the compiler supplied with STOS to write some
small routines for use in STOS; I would also like to use these outside it. These do not have the header that executable files have.
What info should I put before them to make them executable?
	Also: could somebody give me a list of commands for directly turning on the Disk Drive, moving the head to a sector, reading
and writing a block to a sector, formatting a sector etc. I know the addresses $FF86xx are involved in this, but I'm not sure how.

	Any info on both of the above would be appreciated.
