RE: QzshSystem API

["Haas, Matt" <Matt.Haas@xxxxxxxxxxxxxxxxxxx>]

Joel,

The QShell commands all write their output to STDOUT unless you specifically 
pipe the output somewhere else (like a file). On Unix systems when you don't 
care about the output, there's a directory called /dev/null that is usually 
used as the target of the pipe. I just looked at one of our systems and it too 
has a directory called /dev/null. You should be able to pipe the output of a 
command to this and the results just go away.

Some older versions of OS/400 had this directory but it wasn't automatically 
cleared. We're on V5R1 and it seems to work the same as a Unix box now.

True enough, I realize, but I then need to 'cp -r /olddirectory
/newdirectory', something for which I have found no native command.

BTDT...

Unfortunately I'm not creating stdout, I'm copying directory contents. 
I'm not sure overriding stdout would help me in this case.

I appreciate the input, just not sure it will get me where I need to
be.  And naturally, at this point it is a matter of pride to figure out
how to make the API work ;-)

Thanks,
