*'''[[Keywords currently not supported by QB64|Not supported in QB64.]]'''
|
|
* When line number tracing is on, the line numbers of statements are output immediately before they are executed.
|
|
* Use {{KW|TRON}} to turn on line number tracing.
|
|
* Line number tracing only has an effect when programs are compiled with debugging code (BC.EXE /D).
