Description
The amount of CPU time in milliseconds left before Model 204 automatically logs out all users and shuts itself down
For z/VM and z/VSE, Model 204 execution time cannot exceed 24 hours. TIMELEF is set to the value of MAXTIME during initialization, and is later tested to determine how much execution time remains. Unless TIMESTOP (whose default is 1500) is set otherwise, Model 204 shuts itself down when there are 1500 milliseconds left.
For z/OS, Model 204 execution time can exceed 24 hours. Under z/OS, MAXTIME is set to the value of the JCL EXEC statement parameter TIME. If TIME is set to 1440 (that is, 24 hours), z/OS does not automatically shut down Model 204 after 24 hours; if TIMESTOP is set to 0, Model 204 does not automatically shut itself down. When both TIME is 1440 and TIMESTOP is 0, Model 204 continues to run indefinitely until brought down by other means.
When TIMESTOP is greater than zero, TIMELEF protects against file damage due to cancellation of Model 204 by the operating system. Shutdown occurs before the operating system can take action.
