The value of this variable is returned when an ACCEPT FROM INPUT STATUS statement is executed on a machine that cannot determine the input status of the terminal. This can be used to make a running program behave correctly on a new machine. The value must be a single digit. The default value is 0.

If the input is redirected (not attached to a terminal), the SCRIPT_STATUS configuration variable determines whether ACCEPT FROM INPUT STATUS returns the value of INPUT_STATUS_DEFAULT or returns the actual status of the input file.
