The JCLs are built starting from CBTESUB2 skeleton, which can be customized. The structure of the skeleton comprises a single part that is repeated once in the created JCLs, and is delimited by the following keywords:
|
//* UNLOAD ELABORATION and //* UNLOAD END ELABORATION, by the keywords: //* SINGLE FILE ELABORATION and //* SINGLE FILE END ELABORATION and by the keywords: //* DELETE ELABORATION and //* DELETE END ELABORATION is repeated for each file. |
In the skeleton some variables are used, and they are changed into the JCL values using the values stored in the Knowledge Base or included in the launch parameters.
The following table describes the used variables:
