Change Bar Notation
Change bars are used to indicate substantive differences between this manual and its 
preceding version. Change bars are vertical rules placed in the right margin of changed 
portions of text, figures, tables, examples, and so on. Change bars highlight new or 
revised information. For example: 
The message types specified in the REPORT clause are different in the COBOL85 
environment and the Common Run-Time Environment (CRE).
The CRE has many new message types and some new message type codes for 
old message types. In the CRE, the message type SYSTEM includes all messages 
except LOGICAL-CLOSE and LOGICAL-OPEN.
