A: End Date
The End Date is the month, day, and year your event stops being active. See the D:
Start Date section for syntax.
Examples:
D:01.01.2001
D:01/01/2001
D:01-1-2001
R: Repeat Number
The Repeat Number acts differently depending on what other fields it is used with:
• With no Repeat set field present.
• With a Repeat Set field present:
1. With no Repeat set field present:
This is the most common usage of the Repeat Number. It acts as a multiplier
of the
Repeat Period. They should be read in conjunction like this: “Repeat this event
every <repeat number> <repeat period>”. Ex.“Repeat this event every 30
minutes”.
The repeat number can be anywhere from 1 to over 4 billion. You can specify
repeating a number of minutes, which is why this is so huge. Realistically though, you
would specify repeating in years, if it got that large. Whatever combination you
choose between Repeat Number and Repeat Period should not multiply out to be
greater than a century.
Example:
R:1 ;do it every period
R:117 ;do it every 117 periods
2. With a Repeat Set field present: The Repeat Number and the Repeat Period
become an index of the set. These three fields should be read in conjunction like this:
“Repeat this event every <repeat number> <repeat period> in <set>.”
Ex.“Repeat this event every 4
th
Thursday in November.”
Although there are many possibilities, we can use an example of holidays to explain
what using a set can do for you. Over the period of a year, you may want to schedule
events for some holidays. Unfortunately, not all holidays land on the same date every
year. By defining a set, along with the repeat number and repeat period, you can
choose the first Monday of the month, or whatever you like. Sets can be specific or
general.
Example:
R:2 P:Sunday S:May E:Command 1:"1PL" ;Every 2
nd
Sunday in May Play video #1
R:1 P:Day S:Month E:Command 1:”2PL” ;Every 1
st
day of every month play video #2
R:2 P:Day S:Month E:Command 1:”4PL” ;Every 2
nd
day of every month play video
#4
R:3 P:Day S:Month E:Command 1:”5PL” ;Every 3
rd
day of every month play video #5.
….
P: Repeat Period
The Repeat Period defines how long to wait. It is multiplied or indexed according to
the presence of a Repeat Set field. (See the Repeat Set and Repeat Number sections
for details)
