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.

Tests
50 test programs in tests/programs/. Run the full suite:
bash tests/run_tests.sh
Each test has a 5-second timeout. When .expected files are present
(generated from real GWBASIC.EXE), the runner also reports compatibility
match status.
Compatibility Testing
Compare output against real GWBASIC.EXE running under DOSBox-X:
# Generate .expected files from GWBASIC.EXE (requires DOSBox-X Flatpak)
bash tests/run_compat.sh --generate
# Compare gwbasic output against .expected
bash tests/run_compat.sh
CI
GitHub Actions runs on every push to main and on pull requests. The workflow
builds the project with PulseAudio support and runs all 50 test programs.
