Once data description specifications are written, they must be put into a source file. Then, database or device files are created by entering the CL command that starts the data description processor. The CL command can be entered interactively or in a batch job. The data description processor retrieves the data description specifications from the source file designated on the create-file command, validates the specifications, and creates a computer printout with any errors and any referenced specifications.
An example of a data description specifications compiler computer printout follows:
