Pase environment from a batch cl

Hello. I'm trying to automate an SCP connection using the PASE environment.
My problem is that I do not want the terminal to ever come up.  I would
rather log any messages to a file or catch them in my program.  When I have
a file to receive, this works great.  The transfer is completed entirely in
batch.  But if the file I'm trying to transfer does not exist, then I have
the terminal window pop up with an error message, requiring user
intervention.

Any suggestions or tips for me?

Thanks!
Mark
