I'm considering adding some more muscle my VED text editor by permiting it to
access extension modules. The plan is to have a command os9exec() to a user
supplied program which could do "whatever". VED would pass a number of params
to the user program, including the start and end of the text buffer and
pointers to a number of internal routines (the menu routines, etc.). The user
program could then access the text in memory and use the same interface to make
a very transparent extension. I suppose a possible extension could be a
spelling checker...but that's not important.

Questions:

1. Under systems with MMUs is the memory of the parent process available
   to the child?

2. Just what kind of params should be passed to the child? The params would
   be accessed via argc, argv[] routines since I plan to have extension
   just be a standard C program; no complicated subroutines, etc.

So, any suggestions or comments?
