Doas

Thanks for the tutorial on scheduled tasks ..

As for this..
The suggestion to use a message box won't work because the program is normally started by Windows, middle of night, and there is no one to respond to the message.
.. while I didn't explain very well, the "will enter .. in 10 seconds"
was meant to convey that if no action is taken (ie, neither button
is pressed), then the msgbox would "turn off" and normal ShellandWait
would proceed.

This is, I guess, equivalent to your answer 'OK' idea in your OP.
Natch, some sort of timer would be needed here.

And, as for this..
As I said, it could simply be something like initiating a wait loop, during which the user could hit ESC or some combination of keys that would exit the routine before the 'ShellandWait' is executed.
... more questions:
  • this would happen during the day, right?
  • the user would have manually launched the WB, right?
  • how would this interfere with the DOS batch command
    that would occur later, at night?
