Script Not working

I'm new to Winscp but was able to set it up successfully. I can login to another server manually but my problem is getting a script to do the same. Here's my script:

C:\progra~1\winscp3\winscp3.com
open my5.server.com
username
passphrase password
put d:\mydir\*.txt
close

When I run this as a script all I get is:
C:\program files\winscp3\winscp3.com
winscp>_

How do you run the winscp with script?
