Job Entry Subsystem (JES), [1] aka Job Entry Subsystem 1 (JES1), was released by IBM as an integral part of OS/VS1 as an enhancement to the basic functions that users of VS1's predecessor, MFT, had. History
At the end of the job it would regain control and load and run the next until the batch was complete. Often the output of the batch would be written to magnetic tape and printed or punched offline. Examples of monitors were IBM's Fortran Monitor System, SOS (Share Operating System), and finally IBSYS for IBM's 709x systems in 1960. [1] [2]
The Job Entry Subsystem (JES) is a component of IBM's MVS mainframe operating systems that is responsible for managing batch workloads.

IBM's chief executive said in May that the company would slow hiring for some of its roles, particularly in HR, where Candy says the vast majority of staff conversations now happen with a bot.
Job Control Language (JCL) is a scripting language used on IBM mainframe operating systems to instruct the system on how to run a batch job or start a subsystem. [1] The purpose of JCL is to say which programs to run, using which files or devices [2] for input or output, and at times to also indicate under what conditions to skip a step.
IBM Spectrum LSF (LSF, originally Platform Load Sharing Facility) is a workload management platform, job scheduler, for distributed high performance computing (HPC) by IBM. Details [ edit ]
A job scheduler is a computer application for controlling unattended background program execution of jobs. [1] This is commonly called batch scheduling, as execution of non-interactive jobs is often called batch processing, though traditional job and batch are distinguished and contrasted; see that page for details.
