I recently purchase a used Atari that came with some software, but
no documentation.  I am curious if anyone has a set of command summaries
for 
    1) OS/A.  I've figured out a few things: the largest of which is that
       even with my limited knowledge of this DOS, it is much more usable
       than ATARI DOS.  The 'DIR' command alone improves things greatly.

    2) ASM/ED cartridge:  I don't need pseudo-ops, just
       commands to give at the EDIT prompt: (I've figured out ASM and
       LIST) but that's about it.  How do I execute assembled code?
       Trace?  I think you'd get the idea.

Further, is anyone out there aware of any public-domain (hopefully macro)
assemblers?

I anxiously await having my mailbox stuffed with information.  (Do use mail,
one posting on this subject is probably enough).
