The DCODE operand on the MODEENT macroinstruction indicates to TSO/VTAM whether a TWX device is a keyboard display or a keyboard printer. If you specify DCODE to indicate that the device is a keyboard display, TSO/VTAM inhibits the display of the password when the password is entered at the device.
