Inputs, Outputs and Parameters

Inputs, outputs and parameters are defined as follows:

•	An input or output can be a simple data type, such as a string or integer, or a user-defined data type, such as a channel or result. Inputs or outputs defined with user-defined data types facilitate the building of a scalable process.

•	Parameters are invariants of a task, and are independent of inputs and outputs.

•	Any task in a process can include inputs, outputs and parameters.

Examples

The following examples describe the inputs, outputs and parameters associated with the tasks of a process.

A task in a simple math calculator process includes the following inputs, outputs and parameters:

Task	Input	Output	Parameters
Math	Data-1, Data-2	Results	Add, Subtract, Multiply, Divide

Graphically the math task is represented as follows:

math_task_data

A task in a process for a CAE Load Data Signal Analysis includes the following:
