Explanation

OPZERO (Operational Program Zero) is the core z/TPF control program responsible for creating, initializing, and activating the Entry Control Block (ECB) when an input message or process start is triggered. SYSOP, CTRLPGM, and SYSPGM are not the names of this specific TPF control program.
