8. Error Messages Run-time messages are sent to the module’s “log”
Startup messages
Log message indicator
Gray: no messages
Red: error
Blue: warning/remark

9. Debugging Networks FieldInfo: stats on the field
ShowField: display the field
DataIO: save field to disk… emacs!
autoexecute: enabled/disabled
Pipe-trace: where does this go?
Message Log: errors, warnings
Usual suspects: threads, memory
cvd / gdb / dbx: step through code
printf / cerr: when all else fails
