a little help requested with winscp command line parameters

I have nearly all of what I need working with this command

winscp.exe scp//root:mypassword@123.456.789.012/var/log/data/test.dat c:\test.dat

I get attached to the server just fine but them winscp goes interactive on me and asks where I want to store the retrieved file.

is there anyway to bypass the interactivity and store the file in a location without being asked like on regular linux scp command?

Use scripting. See documentation.
