#There was something in a recent PC Magazine about this.  If memory

#the ctty command, then explicitly direct any output you want to appear
#on the screen to CON. eg. "echo Enter Y or N > CON".  Be sure to use
#ctty to redirect output back to CON before ending your batch file.

I hate to think what would happen if your user breaks out of the batch
file.  Is it really that important to hide one line?
