Confirm

Ask user for Yes/No confirmation.

Used in a bat file to set errorlevel to 0 if user answers Y,

or 1 if N.

echo Do you really want to do this dangerous thing?

confirm

If ERRORLEVEL 1 GoTo NO

GoTo YES

The confirm.exe version also looks for SET confirm=y or SET

confirm=n. If it sees it, the user does not need to key anything. It

acts as if the user had hit the Y or N.
