job-control language
Noun: A specialized, problem-oriented computer language used to precisely describe the requirements and steps of a computational job (such as a batch of programs to run) to an operating system. It provides instructions for managing resources, sequencing tasks, and handling input/output.
Noun: * The programmer wrote a detailed script in job-control language to automate the nightly data processing. * Early mainframe systems relied heavily on job-control language to manage batch operations. * Understanding the system's specific job-control language is essential for submitting complex computational jobs.
- JCL (Acronym): "Job-control language" is almost universally abbreviated as JCL, especially in the context of IBM mainframe systems (e.g., z/OS JCL).
- Example: She is an expert in writing and debugging JCL for the production environment.
- Job Control (n): The general function or capability of managing jobs within an operating system.
- Example: The system's job control allows for prioritizing important tasks.
- Batch Language / Shell Script: While not exact synonyms, these are related concepts. A batch language (e.g., Windows Batch) or shell script (e.g., Bash) can perform similar job-control functions in different operating system environments.
- Command Language: A broader term for a language used to control an operating system or program, which encompasses job-control languages.
- Job Command Language
- Control Language (in specific system contexts)
- Job Scripting Language
This term is highly technical and primarily used in the field of computing, specifically in the context of large-scale, batch-oriented operating systems. Its most famous and common instantiation is the JCL used with IBM OS/360 and its successors. In modern contexts, its functions are often performed by more general-purpose scripting or workflow languages.
