Giving an APRM a value
You can think of an APRM as an empty bucket. You can store anything you want in the bucket for later use,
but your bucket starts out empty. DoStudio Authoring includes a number of system actions for use with
APRMs.
For a complete description of the system actions, see "System actions" on page 122.
Using APRMs in a condition
Unlike the conditional fields included with DoStudio Authoring, which evaluate an empirical parameter or
state of the disc (Current Chapter, Is Main Menu On Screen, etc.), an APRM is a customizable variable that
can be compared to any type of value. Commonly, authors will assign integer values to APRM using actions
and then use conditions to evaluate the number value of the APRM and execute a command based on that
number. In this manner, APRMs are quite similar to GPRMs in DVD.
