Change Bar Notation

!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 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.
