 Except old programs that don't follow that `standard' will still be stuck
 with large oddities in their environment.

 By cluttering the environment with yet another variable?  Great.  That's
 just what's needed - even more flot.

 If they know about the commandline in the basepage, why should they need
 upgrades?

 It cuts both ways.  Those of us who use the other ways to pass arguments
 around may end up having to modify our code to work properly with the
 new standard, whatever it may be.

 Why?  I've got programs that don't use xArgs and they coexist just fine
 with xArgs.  I cannot imagine that the MWC `standard' works out any
 differently, except for the magical appearance of garbage in the
 environments of the (non-conformant) child processes.

 And you may be forgetting how many shareware programs use xArgs.
 Considering that dlibs and Sozobon C both use xArgs, the percentage
 of programs using that `standard' will grow.

 Your comment that real argc/argv should be a extention to Pexec() is
 correct, and I agree that it's what Atari should be doing.  But saying
 that the MWC style should be the second choice because it's `there' is
 like saying "we can't fix Malloc() because people take advantage of
 the broken code."

 At risk of sounding like a broken record, I'll note again that one of
 the reasons that Dalnefre', John Stanley and I made up the xArgs method
 is that we (well, *I* - I dunno about Dale and/or John) didn't think that
 the MWC method was worth it's weight in fetid dingos kidneys.  Cluttering
 up the environment with untracable arguments and iovector `stuff' is
 about as unaesthetic as you can get.
