Binary SAVE/LOAD: SAVE now writes tokenized binary by default (0xFF header format), matching original GW-BASIC behavior. SAVE "file",A for ASCII. LOAD auto-detects binary vs ASCII from the first byte. Command-line file loading also auto-detects, so binary .BAS files just work. INKEY$ extended keys: arrow keys, Home/End/PgUp/PgDn, Insert/Delete, and F1-F10 now return the correct CHR$(0) + scan_code two-byte sequences per the IBM PC convention. Refactored event trap key parsing to use tui_read_key() instead of duplicating escape sequence parsing. Golden-file regression tests: generated .expected output files for 55 of 58 test programs (3 timing-dependent tests excluded). The test runner now reports compat match status alongside pass/fail. Classic programs: added Hamurabi, Lunar Lander, Gunner, and Diamond from David Ahl's BASIC Computer Games (1978) in tests/classic/ for manual compatibility testing. Docs updated with compiler roadmap item and hardware I/O simulator plan.

Tests
58 test programs in tests/programs/, plus 4 classic interactive programs in
tests/classic/ (Hamurabi, Lunar Lander, Gunner, Diamond from David Ahl's
BASIC Computer Games).
Run the full automated suite:
bash tests/run_tests.sh
Each test has a 5-second timeout. 55 tests have .expected golden files
for output regression detection. Three timing-dependent tests (datetime,
on_timer, timer_stop) run without golden comparison.
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 58 test programs.
