TIMER

        [SIC\]TIMER
        [SIC\]TIMER ON|OFF
        [SIC\]TIMER [Time [Unit]] [/COMMAND String]

    All Gildas programs can be automatically closed (normal  exit)  after  a
    defined period of inactivity at the prompt level. This period is defined
    by the Sic timer. The timer starts as soon  as  the  program  prompt  is
    available  (i.e. inactivity). The timer is stopped when a command starts
    running. It restarts from the beginning when the  prompt  is  back.  The
    timer is unset (i.e. no timer) by default.

    Without argument, display the timer status.

    With the keyword ON or OFF as argument, enable or disable the timer. The
    timer is enabled by default.

    With a Time argument, set the timer to the input value. Unit is  a  key-
    word which can be HOURS, MINUTES, or SECONDS (default HOURS).

    The  command  executed once the timer is done can be customized with the
    option /COMMAND. The command string must be a single argument,  possibly
    double-quoted if blanks are needed, e.g.
      SIC> TIMER /COMMAND EXIT
      SIC> TIMER /COMMAND "EXAMINE PI"
      SIC> TIMER /COMMAND "SAY ""Hello from timer"""
    Default command at startup is EXIT.

    The  timer  duration  can be customized in a Sic logical named SIC_TIMER
    (integer value, in hour unit). This value is evaluated once  at  startup
    from one of the Sic logical dictionaries. Later changes are ignored.
