Diskette File Organization (Exchange Media, Part 2: Diskette Transfer)
Files may be organized for a transaction in one of three ways:
single volume, multiple files
multiple volumes, multiple files
Each single diskette constitutes one volume. Record blocking is not used and individual records do not span files or volumes. Files do not span volumes. Large logical files of records can be segmented into multiple physical files on separate volumes. The following configurations may be used. NOTE: The names in parentheses are required filenames. The notation nnn represents sequential numbers determined by the originator of the volume(s)/file(s).
Single volume, Single file: Volume Label File (VOL.nnn) File Label File (FIL.nnn) |
Single volume, Multiple files: Volume Label File (VOL.nnn) File Label File (FIL.nnn) Bibliographic File File Label File (FIL.nnn) Bibliographic File |
Multiple volumes, Multiple files: |
