CCSS

CCSS architecture centers on integrating control card specifications directly into z/OS JCL. The main component is the JCL preprocessor, which interprets the CCSS syntax within the JCL. , //SYSIN DD *) and the subsequent control card statements.

The preprocessor then formats these control cards for the target utility, such as IDCAMS or IEBGENER. Communication between the JCL preprocessor and the utility is handled through the standard z/OS input mechanisms, typically SYSIN. There are no specific APIs exposed by CCSS.

The primary interface is through JCL syntax. CCSS does not use any specific databases or storage mechanisms. It relies on the z/OS environment for dataset access and management.

Network requirements are minimal, as CCSS operates within the z/OS environment. Security relies on z/OS security features, such as RACF, to control access to JCL and datasets. Compared to using DD DATA or DD *, CCSS provides greater flexibility and control, especially when dealing with complex control card requirements.

The key advantage is the streamlined integration of control cards, enhancing JCL readability and reducing dataset management overhead. The preprocessor ensures that the control cards are correctly formatted and passed to the target utility for processing.
