Gee, I bought $300 worth of documentation from Atari itself and it doesn't
seem to have the correct method of invoking Pexec() in it.  I still haven't
figured it out.  Presumeably, mode 4 (create basepage) would return a basepage
address.  Does the Atari documentation mention this?  No.  Once one has a
basepage address how does one subsequently invoke Pexec() with this address
and what other arguments are then used with the call?  The Atari documentation
doesn't say.  Rumor has it that Mshrink() must be invoked to give the called
process memory to execute in.  Does the Atari documentation mention this?  No.
How does one calculate how much memory to keep in the invoking program and
starting from what address?  The Atari docs don't say.

It seems a little ridiculous that after paying $300 for docs that I would
have to pay X more dollars to either buy more docs or to get onto Compuserve
to see the corrected docs.

Is there some gratis method of getting the correct documentaion for Pexec(),
Allan?
