RND can now be called without parentheses (equivalent to RND(1)), matching real GW-BASIC behavior for legacy code compatibility. Update all Sphinx documentation pages to reflect features added in v0.6.0-0.8.0: DATE$/TIME$/TIMER, FILES/SHELL/CHDIR/MKDIR/RMDIR, AUTO/RENUM/DELETE, COMMON, LPRINT/LLIST with --lpt, --full TUI flag, dynamic screen buffer, 54 tests.

# 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** — dynamically sized screen buffer (25×80
|
||
default, full terminal with `--full`), 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/COMMON
|
||
- **Printer output** — `LPRINT`/`LLIST` to file or real hardware via `--lpt`
|
||
- **54 test programs** with DOSBox-X compatibility testing against real GWBASIC.EXE
|
||
- **MIT License**
