You might also want to take a look at seek, tell, and truncate. You can lock the file, open it once with +>> (read/write access in append mode, so you don't blow away whatever's already in there), then use these calls to do everything you need to do before closing and unlocking the file.

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
