! CONTROL.SCR
!
! This script manages some independent functions of the game system.  The
! script is called by the game driver at certain points during game play,
! and the entry points are numeric (@0, @1, @2..) instead of the usual entry
! points (@TALK, @GET, ..).
!
! QUICK SUMMARY OF ENTRY POINTS:
!
! :@0 - Time Control.  Executed once every minute (game time).
! :@1 - Resting.       Executed when party decides to rest ('C'amp-Out)
! :@2 - Leave Party.   Removes a party member. ('V'acate command)
!

!---------------------------------------------------------------------------!
:@0 ! Entry Point @0 : Time Control Script                                  !
!---------------------------------------------------------------------------!
!
! This script will start execution at this label once per minute during
! regular play.  This does not include battles or when the party is resting.
!
! Time is controled by seting the following variables from any script:
!
!   Variable             Default  Description
!   -------------------  -------  --------------------------------
!   MovesPerMinute             2  # of moves per game 'minute'
!   MinutesInAnHour           60  # of minutes in an game 'hour'
!   HoursInADay               24  # of hour in a game 'day'
!   DaysInAMonth              30  # of days in a game 'month'
!   MonthsInAYear             12  # of months in a game 'year'
!
! The CURRENT time is obtained (and modified) by setting the following
! variables:
!
!   year                 Current Year   (Range -32767 to 32767)
!   month                Current Month  (Range 0 to MonthsInAYear - 1)
!   day                  Current Day    (Range 0 to DaysInAMonth  - 1)
!   hour                 Current Hour   (Range 0 to HoursInADay   - 1)
!   minute               Current Minute (Range 0 to MinutesInADay - 1)
!
! Note that the year, month, day, hour and minute variables are automaticly
! updated by the game driver, but you can modify these variables just like
! any other one.
