## Summary  
Control Language (CL) is an IBM operating system scripting language used primarily for communicating instructions to machines. It is designed for IBM i (formerly OS/400) and Control Program Facility (CPF) systems, offering imperative programming capabilities. Developed by IBM, CL is integral to managing and automating tasks on IBM Power Systems.

## Key Facts  
- **Developer**: IBM (inception: 1911, headquartered in Armonk, USA).  
- **Parent Systems**: Part of IBM i (launched in 1988) and Control Program Facility (CPF).  
- **Type**: Imperative programming language (references: Wikidata).  
- **Aliases**: IBM i Control Language, CL, CLLE, AS/400控制语言.  
- **Freebase ID**: `/m/027sj6` (verified).  
- **Sitelink Count**: 3 (Wikidata).  
- **Wikipedia Coverage**: Available in German, English, and French.  

## FAQs  
### Q: What is Control Language used for?  
A: Control Language is used to script and automate tasks on IBM i and CPF operating systems, such as system management and batch job execution.  

### Q: Is Control Language still in use today?  
A: Yes, CL remains actively used on IBM i systems, particularly in legacy enterprise environments running IBM Power Systems.  

### Q: What programming paradigm does Control Language follow?  
A: CL follows an imperative programming paradigm, where commands are executed sequentially to perform specific operations.  

## Why It Matters  
Control Language plays a critical role in IBM’s ecosystem, enabling administrators and developers to interact with IBM i and CPF systems efficiently. Its scripting capabilities streamline system management, reducing manual intervention for repetitive tasks. As a legacy language, CL supports long-standing enterprise applications, ensuring backward compatibility for businesses reliant on IBM Power Systems.
