Meta data is a term used to describe the method by which a user can access internal CatTools variables or functions from within an Activity.
Meta data should not be confused with Filename Variables.
The meta data commands / variables are placed within the stream of commands defined by the user for the Activity.
They may be the only command for an Activity but would normally be interspersed amongst actual device commands.
The commands are evaluated by CatTools for each device in the Activity list and tell CatTools to either :
1) Perform a CatTools internal action at that point in time. A Meta Command.
2) Or replace the variable with an actual data value. A Meta Variable.
Activities that support the use of Meta data include :
