Does that work if a "return" or "enter" is pressed?Quote from: Aegis on April 07, 2009, 04:13:21 PM

Does that work if a "return" or "enter" is pressed?

It will ONLY work if Enter/Return is pressed. The set /p command requires either a string of characters terminated by Enter, or Enter alone. The "null string", represented by "", is another way of saying "Enter".
THANK you -- appreciate the explanation!That worked! Thanks for your help.
