Exchange format has always existed for ZEBRA FZ files. However, due to limitations of certain FORTRAN implementations, such files have not been easily transferable to/from these systems. (FORTRAN typically writes control words at the beginning and end of each record in sequential files on most Unix systems. These control words render the file unreadable from other systems across NFS, or if the file is transferred using FTP without further conversion). ZEBRA FZ has now been enhanced to provide I/O using the C run time library (or FORTRAN direct-access I/O). Files written with either of these options maybe be shared across systems using NFS or transferred using FTP without further conversion.
