• math_quiz.bas - Math quiz game (WHILE/WEND, EXIT FOR, ABS, SGN, RANDOMIZE, RND)
• lunar_lander.bas - Classic lunar lander game
• simple_lunar.bas - Simplified lunar lander

• string_lab.bas - String laboratory: Caesar cipher, word counter, base converter (MID$, ASC, CHR$, INSTR, VAL, STR$, SQR, RESTORE, ON...GOSUB)

• address_book.bas - Contact manager with save/load (OPEN, CLOSE, PRINT#, INPUT#, LINE INPUT, EOF, ON ERROR GOTO)
• graph_chart.bas - Graphical bar chart from file data (OPEN, INPUT#, PRINT#, PMODE, LINE, PAINT, PSET, ON ERROR GOTO)

• bounce_pause.bas - Bouncing animation with PAUSE command
• blue_circle.bas - Graphics circle demo

Use the LOAD command in the CLI or web interface:

LOAD "lunar_lander"        # Loads lunar_lander.bas (auto-adds .bas extension)
LOAD "lunar_lander.bas"    # Explicit filename
LIST                       # View the loaded program
RUN                        # Execute the program

The LOAD command searches for programs in this order:

1. Current working directory
2. programs/ subdirectory
3. Project root directory
4. Project root programs/ directory

1. Create a new .bas file in this directory
2. Use line numbers (10, 20, 30, etc.)
3. Save and load with the LOAD command

Or use the SAVE command from the emulator:

10 PRINT "HELLO, WORLD!"
20 END
SAVE "myprogram"
