Each TIMELINE data member is defined as follows:
Return Valuess:
Example:
DEFINE_VARIABLE
LONG TimeArray[100]
DEFINE_CONSTANT
TL1 = 1
TL2 = 2
DEFINE_EVENT

Timeline representation
ID The ID that the user assigned to the timeline in the TIMELINE_CREATE func-
tion.
SEQUENCE The index of the time in the Times array that was passed to the
TIMELINE_CREATE function. The SEQUENCE data member is used to deter-
mine what action to take for the event and is normally decoded with a SWITCH/
CASE structure (as shown in the example).
TIME The amount of time that has elapsed since the timeline started. For repeating
timelines, the TIME and REPETITION data members can be used to calculate
the total amount of time it has been running.
RELATIVE If the timeline is operating in relative mode, this data member is equal to
TIMELINE_RELATIVE. If the timeline is absolute, it is equal to
TIMELINE_ABSOLUTE.
REPETITION If the timeline was created with TIMELINE_REPEAT, this data member holds
the number of times the timeline has been executed. REPETITION contains
zero for the first pass through the timeline. Thus, the calculation to determine
the total amount of time the timeline has been running is simply:
TIMELINE.TIME * TIMELINE.REPETITION.
