The BEFORE TIME phrase allows you to automatically terminate an ACCEPT statement after a certain amount of time has passed.
The timeout value specifies the time to wait in hundredths of a second. For example, "BEFORE TIME 500" specifies a timer value
of 5 seconds.
The user must enter data to the ACCEPT statement before the timer elapses. As soon as the user starts entering data, the timer
is canceled and the user may take as much time as desired to complete the entry. If the user does not enter any data before
the timer elapses, then the ACCEPT statement terminates.
