Computer programming jobs salary

In a non-interactive computer system, particularly IBM mainframes, a job stream, jobstream, or simply job is the sequence of job control language statements (JCL) and data that comprise a single unit of work for an operating system.
The term job traditionally means a one-off piece of work, and is contrasted with a batch, but non-interactive computation has come to be called batch processing, and thus a unit of batch processing is often called a job, or by the oxymoronic term batch job; see job for details.
Performing a job consists of executing one or more programs.
Each program execution, called a job step, jobstep, or step, is usually related in some way to the others in the job.
Steps in a job are executed sequentially, possibly depending on the results of previous steps, particularly in batch processing.
