Performance Notes
Execution speed depends on interpreter implementation
Memory usage is minimal
Programs are usually short but confusing
Optimization is generally not a goal
Program correctness may require unusual logic reasoning
Security Notes
Runs locally in interpreter; no network access by default
Minimal risk of malicious code
Errors are usually runtime confusion or crashes
Memory is controlled by interpreter
Safe to experiment in sandboxed environment
Monitoring Analytics
Trace memory cell values
Track execution steps and flow
Debug using interpreter messages
Compare program efficiency and length
Analyze output correctness
Code Quality
Ensure proper use of COME FROM statements
Maintain consistent politeness keywords
Comment with external notes for readability
Test output incrementally
Keep programs concise for challenge purposes
