I disagree completely. People should use the documented OS calls. They 
shouldn't fumble around inside the Operating System looking for calls and 
data structures that weren't intended for their use.

I can't believe what I am hearing! You state my case for me. Programmers 
depended on the things they read in the IBM disassembly and when things 
changed their code broke! Isn't that a good enough reason for not releasing
disassembled or source versions of sections of the Operating System? 

My job at Atari is support. I am one of the people that has to take calls 
from irate customers that are mad because their favorite program breaks on
their new computer (with MEGA TOS ROMs) and I am the one that has to tell 
them that it's because the manufacturer of the software didn't follow the 
rules when writing his/her program. Most of the time, Atari gets the blame 
(in the customer's eyes) for these problems with software, when in reality
it's the software that is at fault.

Anyway, there's my position on disassembled versions of TOS.
