The most significant of these new features were the history and editing mechanisms, aliases, directory stacks, tilde notation, cdpath, job control and path hashing.

The job control statements were themselves subsequently run to compile the other elements and create an integrated system of database, applications, and user terminal network.

These were accordingly referred to as jobs, as they were one-off processing, and were controlled by languages such as Job Control Language ( JCL ).
24.
Transfers can be scheduled for execution at a later time, bandwidth can be throttled, transfer queues can be created, and Unix shell-like job control is supported.

For example, improving job satisfaction can reduce 17-69 per cent of work-related back disorders and improving job control can reduce 37-84 per cent of work-related wrist disorders.

I also tried to make the job control aspects of the system independent of the language implementation, and that aspect of the project may be of interest.

28.
The C shell's job control allowed the user to suspend the current activity and create a new instance of the C shell, called a job, by typing background.
29.
The LINC system created 3rd GL COBOL ( application ), DMSII ( database definition ), NDLII ( network description ), and WFL ( job control ) source code.

While the OS 2200 job control language does not support full programmability, it does allow dynamic additions of sequences of control language through an @ ADD control statement.
