Files may be organized for a transaction in one of three ways:

single volume, single file

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).
