The JCLs are built starting from CBTELOD1 and CBTELOD2 skeletons, which can be customized. The CBTUNLD2 skeleton is an alternative skeleton where the UNLOAD utility is used instead of the DSNTIAUL utility in order to create SYSPUNCHs .
The structure of the skeleton comprises a starting and ending part that are repeated once in the created JCLs, and a central part that is delimited by the following keywords:
|
//* SINGLE FILE ELABORATION and //* SINGLE FILE END ELABORATION, that 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:
| Variable | Description |
