Change Bar Notation
Line Spacing. If the syntax of a command is too long to fit on a single line, each
continuation line is indented three spaces and is separated from the preceding line by
a blank line. This spacing distinguishes items in a continuation line from items in a
vertical list of selections. For example:
ALTER [ / OUT file-spec / ] CONTROLLER
[ , attribute-spec ]...
!i and !o. In procedure calls, the !i notation follows an input parameter (one that passes data
to the called procedure); the !o notation follows an output parameter (one that returns
data to the calling program). For example:
CALL CHECKRESIZESEGMENT ( segment-id !i
, error ) ; !o
!i,o. In procedure calls, the !i,o notation follows an input/output parameter (one that both
passes data to the called procedure and returns data to the calling program). For
example:
error := COMPRESSEDIT ( filenum ) ; !i,o
!i:i. In procedure calls, the !i:i notation follows an input string parameter that has a
corresponding parameter specifying the length of the string in bytes. For example:
error := FILENAME_COMPARE_ ( filename1:length !i:i
, filename2:length ) ; !i:i
!o:i. In procedure calls, the !o:i notation follows an output buffer parameter that has a
corresponding input parameter specifying the maximum length of the output buffer in
bytes. For example:
error := FILE_GETINFO_ ( filenum !i
, [ filename:maxlen ] ) ; !o:i
Change Bar Notation
Change bars are used to indicate substantive differences between this edition of the
manual and the preceding edition. 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.
