REMINDERCHECK can be started from shell simply by typing ReminderCheck and pressing Enter. You can also type ``FILE=filename'' as a command line argument to specify the database file22 to be used. The other possible command line arguments are ``INTERVAL=# of hours'' which defines the minimum numbers of hours between two remindings, ``NOREQTOOLS'' which causes REMINDERCHECK not to use ReqTools.library, ``MAXGROUP=# of events'' to specify maximum number of events in group requester, ``MAXWIDTH=# of chars'' to specify maximum width of line and ``NOAREXX'' which causes REMINDERCHECK not to open RexxSysLib.library and thus not use ARexx.
