Passing Parameters Between Services within a DSP
To pass data between services within a DSP, you can use any of the following techniques:
Invoke the service that needs the parameter within the scope of the service that produces the parameter. When a service is invoked in a DSP, it receives all of the variables that are “in scope” at the point where it is invoked. For an example of this, see the sample code on .
Use the
%rename% tag to copy a variable that is out of scope into the current scope. For details and examples, see the
%rename% tag description on
%rename%.
Use the
%scope% tag to add a variable to the current scope and specify its value. For details and examples, see the
%scope% tag description on
%scope%.
