          you are likely to run into on BBSs. The program to
          uncompress these files can also be found on BBSs. Today,
          the vast majority of Bulletin Board System OPerators
          (SYSOPs) use PKZIP to ZIP their IBM files. See the next
          section for "How to Unzip Zipped Files."

                  will want the latest version to insure complete
