Add event-driven programming: ON TIMER(n) GOSUB with TIMER ON/OFF/STOP, ON KEY(n) GOSUB with KEY(n) ON/OFF/STOP for F1-F10. Fix F-key escape sequence parser (F9/F10 detection, push back consumed bytes on unmatched sequences). Add EDIT statement for TUI line editing. Guard key trap polling so keystrokes aren't consumed when no traps are configured.

Roadmap
Planned Features
- BSAVE / BLOAD — binary file save/load for screen buffers and data
- DEF SEG — memory segment declaration for PEEK/POKE/BSAVE/BLOAD
- PRINT USING edge cases —
**asterisk fill,**$combined - Binary SAVE/LOAD — Protected (,P) and tokenized binary formats
- GET/PUT graphics — sprite capture and blit for graphics mode
- TUI color support — map GW-BASIC COLOR attributes to ANSI 16-color output
- INKEY$ extended keys — return CHR$(0) + scan code for arrow keys and function keys, matching the original two-byte encoding
- VIEW / WINDOW / PALETTE — graphics viewport, coordinate mapping, and palette
IDE and Notebook Integration
- Jupyter kernel for GW-BASIC — a Jupyter Notebook kernel that runs
GW-BASIC programs cell-by-cell, with rich output for
PRINT, inline graphics rendering for drawing commands, and interactiveINPUTvia notebook widgets. Similar in spirit to foxkernel. - JetBrains plugin (IntelliJ/CLion) — full-featured language plugin with
syntax highlighting, code completion, line number navigation, run
configurations, debugger integration (breakpoints via
STOP, variable inspection), structure view (line number outline), and error annotations. - VS Code extension — language extension providing syntax highlighting (TextMate grammar), snippets, run/debug tasks, integrated terminal runner, and Language Server Protocol support for diagnostics and hover info.
Known Limitations
- No binary/protected file format support (ASCII only)
PEEK/POKEare stubs (POKE parses and discards, PEEK returns 0)- String garbage collection not implemented (uses
malloc/freeinstead) - Maximum 256 variables, 64 arrays, 16 FOR nesting, 24 GOSUB nesting, 16 WHILE nesting
- Hardware I/O (OUT, INP, WAIT, COM, MOTOR) not implemented — no modern equivalent
