Items to Remember
Keep the following points in mind:
- The procname is the name of your TPX procedure that contains the VSAM files you want to process.
- You must allow a region size of at least four megabytes to start the batch facility.
- If you have changed the symbolic parameters for the startup procedure, change VNODE in your VNODE='*BATCH*' parameter to the value specified in the VNODE parameter of your startup procedure. See the Installation Guide.
- Do not use sequence numbers in Batch input statements. Batch statements will not execute if you use sequence numbers. If you are using TSO to create your JCL, enter UNNUM in the command line to turn off sequence numbers.
- You can use the COMMENTS statement to put comments in your control file. You may find it helpful to document the control statements so that other users can easily see what the statements do. COMMENTS statements are not executed when the job is run. For an example containing some COMMENTS statements, see Sample JCL.
- Do not intersperse comments in a command. This can cause parsing errors when batch executes the command. If you want to separate the parameters in a command, use blank lines.
