Ken, your assumption is correct.  I knew what I meant, but didn't
articulate it properly.  The filePro error is the result of a system
command.  The menu script doesn't produce a filePro error.

RY is a user input field; cd is the path to run rreport.  WE is the week
ending date the user selected.

I did not know that.  That explains why it isn't working.

I haven't because I have never heard of that, this is my first foray into
any programming on Windows, I've been using filePro on UNIX for 25 years.
 Is that possible from within processing?
