## Overview

ApacheBAS is a Windows CGI-hosted BASIC interpreter. The documented user workflow is to request a `.bas` page through Apache, which launches the interpreter to execute the script and return an HTTP response. The runtime is a single assembly source file; the README also describes application examples, but the tree exposes them only as an archive. No source excerpts were provided, so the graph includes only documented relationships and does not infer internal call sequences.

Main entry points: [`src/BAS experiments/BAS projects.zip`](https://github.com/gagniuc/apachebas/blob/main/src/BAS%20experiments/BAS%20projects.zip) (Web applications), [`src/ApacheBAS/ApacheBAS.asm`](https://github.com/gagniuc/apachebas/blob/main/src/ApacheBAS/ApacheBAS.asm) (BASIC interpreter)
