Authentic GW-BASIC screen editor with 25x80 buffer, free cursor movement, enter-on-any-line, F1-F10 function keys, Insert/Overwrite toggle, KEY ON/OFF/LIST statement, and Ctrl+Break handling. HAL pointer swap routes all PRINT/LIST/error output through the TUI automatically. Piped mode unchanged (50/50 tests pass). Adds automated compatibility testing infrastructure: DOSBox-X headless config, PRINT-to-file transform script, and run_compat.sh with --generate and --compare modes for verifying output against real GWBASIC.EXE. Project renamed from gwbasic-c to GW-BASIC 2026.

# GW-BASIC 2026
|
||
|
||
A portable C reimplementation of Microsoft GW-BASIC, using the
|
||
[original 8088 assembly source](https://github.com/microsoft/GW-BASIC)
|
||
(released by Microsoft in 2020) as the authoritative reference.
|
||
|
||
This is not a transpilation — it reimplements the algorithms in clean C11
|
||
with modern data structures while targeting bug-compatible behavior.
|
||
Unlike the original assembly (43,771 lines across 43 `.ASM` files), this
|
||
version is structured as modular C suitable for new feature development.
|
||
|
||
## Highlights
|
||
|
||
- **Authentic full-screen editor** — 25×80 screen buffer, free cursor movement,
|
||
Enter-on-any-line, F1-F10 function keys, Insert/Overwrite toggle
|
||
- **Sixel graphics** — `SCREEN 1`/`SCREEN 2` rendering in compatible terminals
|
||
- **Sound** — `SOUND`, `BEEP`, `PLAY` (MML) via PulseAudio
|
||
- **Full file I/O** — sequential, random-access, SAVE/LOAD/MERGE/CHAIN
|
||
- **50 test programs** with DOSBox-X compatibility testing against real GWBASIC.EXE
|
||
- **MIT License**
