Although it is not real execv at all, the way you should give
arguments is the same.

What are the examples you tried?

Actually, execv* should not wait.
They are supposed to invoke other process, 
and let python die at that moment.

Current execv imitation is acting more like spawn(), I guess.

If you want Python to wait, use os.system.

If os.system is giving you problem because of spaces in the pathname,
use "os.systema" contained in updated osce.py attached on this mail.
(I made that function because os.system does not handle pathnames with
spaces in it. And it is the same on desktop Python... )

>>> os.systema('windows/cmd','/k dir *.txt') # invoke command console of HPC
>>> os.systema('/program files/zzz/yyy.exe','arg1 arg2 arg3') # invoke what
ever you want

That may not be possible with the distribution you have.
I think Brad has changed the code so that only one copy of 
Python should run, when he updated (Pythoncore4.zip).

So, either you can use older python22.dll that may not contain _socket,
or you can try to use HPC2000 distribution with PPC specific files from
the distribution Brad has made (Pocket PC Python.exe, win32gui, pcceshell.py).

Later this week or next week, 
I will make trial Cab distribution with above configuration.

Now, I'm working so that command line parameter can be used.
Someone has sent me a patch for it, and I'm compiling and testing.
When I finish that and some other stuffs I wanted to improve,
I'll make new release for HPC2000, and trial distribution for PPC.

New release will include;

  improved pcceshell.py with clear screen, command logging, 
  simple command history,
  slightly better imitation for os.system and os.execv,
  multi-byte pathname, filename support for os.listdir, os.mkdir, etc.
  and commandline parameter support.

Most probably, PPC trial distribution will be able to run 
multiple copy of Python.
