This chapter contains a summary of the language elements which should not be used in new programs because they will not be supported by future COBOL standards. It is advisable to remove these obsolete elements from old programs.
MEMORY SIZE clause:
Only used for documentation (see the section "OBJECT-COMPUTER paragraph").
MULTIPLE FILE TYPE clause:
Required when more than one file shares a tape reel (see the section "MULTIPLE FILE TAPE clause").
RERUN clause:
Indicates when and where the restart points are to be issued (see the section "RERUN clause").
DATA RECORDS clause:
Only used for documentation and specifies names of the records in a file (see the section "DATA RECORDS clause").
LABEL RECORDS clause:
Used to specify the names and values of the labels contained in a file (see the section "LABEL RECORDS clause").
VALUE OF clause:
Defines the description of data items in a label record (see the section "VALUE OF clause").

REVERSED phrase:

STOP literal phrase:
Outputs the literal on the associated main console or subconsole so that only the system operator can resume the program (see the section "STOP statement").
Segmentation:
Segmentation in the PROCEDURE DIVISION to permit program overlay requirements to be specified at compile time (see the chapter "Segmentation").
SEGMENT-LIMIT clause:
Permits the number of permanent and overlayable fixed segments in the program to be varied.
