Creating a List of Values Read and Written (Win32 only)

Each component in a pipeline reads values from the order form, performs its function, and then writes values to the order form. Components that execute later in the pipeline often read values that previous components have written to the order form. When you are modifying a pipeline or creating a new one, it can be helpful to see a list of the values that each component reads and writes so you can ensure that the necessary values are present at each point.

The Win32®-based Pipeline Editor can create a text file that lists each component of a particular pipeline in the order in which it is executed. The text file lists all of the components executed by the pipeline, including the required components that are not displayed in the Pipeline Editor. (The required component always executes last in a given stage.) For each component, the file lists the following information:

• υInput values (values read)
• υOutput values (values written)
• υContext values (values read from the PipeContext Dictionary object, which is passed as a parameter to the pipeline object’s Execute method)

To create a list of all values read and written

1. In the Win32-based Pipeline Editor, open the .pcf file.
2. On the File menu, click Save Values Read & Written.
3. In the Save as dialog box, specify a location and a filename for the text file, and then click Save.

   The Pipeline Editor saves the file and opens it in Notepad.
