|---|---|
| Using goto not as part of an if statement (as in: goto end), will cause initialization to be skipped on all the code the goto jumps over. In performance, leaving some opcodes uninitialized will cause deletion of the note/event. In these cases, using kgoto (as in: kgoto end) might be preferred." |
