## FAQs
### Q: Who developed BASIC-PLUS?
A: BASIC-PLUS was developed by Digital Equipment Corporation (DEC). It was created to provide a programming environment for their computing systems.

### Q: What operating system is required to run BASIC-PLUS?
A: BASIC-PLUS runs on the RSTS/E operating system. This is a timesharing operating system designed for DEC PDP-11 minicomputers.

### Q: How does BASIC-PLUS relate to standard BASIC?
A: BASIC-PLUS is a dialect of the BASIC programming language. It is classified as an imperative programming language and was influenced by the original Dartmouth BASIC.

## Why It Matters
BASIC-PLUS holds a specific place in computing history as a proprietary dialect developed by Digital Equipment Corporation (DEC) for the PDP-11 minicomputer platform. Emerging in 1970, it served as a critical tool for users operating within the RSTS/E timesharing environment. By adapting the accessible nature of Dartmouth BASIC for commercial minicomputer hardware, it facilitated instruction and application development during a pivotal era in computer science. Its existence highlights the era of hardware-specific language variations, where manufacturers like DEC tailored established languages to optimize them for specific system architectures like the PDP-11.

## Notable For
*   **Proprietary Dialect:** Distinct from standard BASIC, specifically tailored by Digital Equipment Corporation.
*   **Platform Specificity:** Designed exclusively for the RSTS/E operating system on PDP-11 minicomputers.
*   **Historical Lineage:** Acts as a direct descendant or variation influenced by Dartmouth BASIC.
*   **Imperative Paradigm:** Utilizes imperative programming commands to communicate instructions to the machine.

## Body
### Development and Classification
BASIC-PLUS is classified as a dialect of the BASIC programming language. It operates under the imperative programming paradigm, meaning it uses statements to change a program's state. The language was developed by Digital Equipment Corporation and traces its conceptual roots to Dartmouth BASIC.

### System Requirements
The utility of BASIC-PLUS is tied directly to the hardware and software environment of the 1970s. It functions specifically on the RSTS/E operating system. RSTS/E is a timesharing operating system utilized by the DEC PDP-11 minicomputers, which were inceptioned around 1970.

### Identifiers and Records
The language is cataloged in several major bibliographic databases:
*   **Library of Congress Authority ID:** sh85012082
*   **Bibliothèque Nationale de France ID:** 11990343t
*   **National Library of Israel J9U ID:** 987007284638705171
