Second Edition (February 1970) .

This edition is a major revision of Form GC28-6398-0 and makes that
edition and its associated Technical Newsletter, Form N28-0263,
obsolete. The specifications in this publication correspond to Release
22/23 of the IBM System/360 Disk Operating System. This edition
contains changes and additions that reflect the Version 2 Compiler's
support of the following features: relative track addressing for direct
files, spanned records on sequential tape files and on direct files, and
forced end-of-volume for a sequentially organized file on a direct
access device. In addition, changes have been made throughout the
publication to correct and clarify specific items. All technical
changes are indicated by a vertical line to the left of the change:
