PARMLIB command

TSO/E provides the PARMLIB command, which lets users list TSO/E options that are in effect on the system and update the options as specified in IKJTSOxx members of SYS1.PARMLIB. You can also use the CHECK parameter of PARMLIB to check the syntax of any IKJTSOxx member of SYS1.PARMLIB including the active member.

TSO/E provides initialization and termination exits that you can use to customize the PARMLIB command. The initialization exit can restrict users from using the PARMLIB command, change operands supplied by the user, or pass the address of a new command buffer. The termination exit can perform clean-up processing, such as releasing storage obtained by the initialization exit.
