2. Modify the contents of the CEEUOPT member you copied.
Modify the contents of the CEEUOPT member you copied to the contents described in Setting parameters in Language Environment (LE) that affect HULFT operations.
3. Assemble the contents of the CEEUOPT member you copied.
JCL template for registration is located in 'CEE.SCEESAMP(CEEWUOPT).'
Define HULFT library in the load module library you will register, and then register the library.
4. Back up the module.
Back up 'XRAPTSRV' and 'XRAPTTSK' in a different location.
5. Statically combine the module into HULFT module.
