[ Type code = E ] Operator may use the Backspace key (when in first position of field) or Escape key to signal abort. Either key displays and returns the field as "END", and sets both inxctl and exitcode to 2. Note that the Left Arrow key takes on a different function when used without the E code; see exitcode. Also note that typing "END" is not supported as an alternative to using Backspace or Escape.
