Problem executing WinSCP Code thru SHELL

I have a batch file, FTP.Bat, in c:\Temp:
> Del zFTP.Txt
> winscp /script=zFTP.Scp /log=zFTP.Txt
> cscript c:\temp\test.vbs
> Exit
and Test.vbs contains MailBox("OK")

When I execute it either as a straight batch file, from the Start_Run line, or as a batch file thru the VBA Shell, I see the "OK" message from cscript.

But when I execute the batch file thru the VBA Shell Command
Call Shell("c:\Temp\FTP.Bat")
then neither the "Del" nor the "Winscp" lines get executed.


Any idea what's going on?
