    A version of the confidence interval calculating program TrawlCI was recompiled to enable it to be run within the DOS emulator of recent versions of the Microsoft Windows operating system. The performance of the recompiled version was compared with that of the original version.
    The recompiled version of TrawlCI produced very similar, though not identical, results to the original version. We attribute this to differences in the minimisation routines of the recompiled version. We conclude that the differences evident from these tests are unlikely to significantly influence the estimated long-term yield of Dissostichus eleginoides or Champsocephalus gunnari
