- JCL cannot manipulate data in any way. In other words, "JCL" cannot perform this task. Only programs that operate in an environment specified by JCL can perform this task.
- Programs like the Changeman product you mentioned use standard programs like an Assembler, compilers and the Binder to affect the binary form of package. In some simple cases a Changeman will use selected low level APIs such as the STOW function to delete a member of a PDS.
- If you direct Changeman to remove a component from a package, it most likely will use the Binder to remove the component from load modules and the STOW function to delete entire members.
- Certainly you can simulate this using ordinary programs outside of Changeman. though you must understand how Changeman inserts the component into the package.
- You should be aware that Changeman will reinsert the component the next time it rebuilds the package. So you should be doing this through Changeman.
