Parameter Passing and the Task Global Data Area (TGDA) |
DEVELOPER |
 |
A Task Definition also defines a Task Global Data Area (TGDA) that can potentially be accessed by any function executed by the Task. This TGDA is described when defining the Task, and is derived from the definition of Task parameters and a work space area potentially available to all Task member functions.
Each parameter defined in the Task Definition has its own named storage area in the TGDA. Additional named space can be reserved by defining global data in the Task Definition. The parameter variable areas and the additional global data areas are collectively known as the Task Global Data Elements (TGDEs).
