Summary -

In this topic, we described about the Working-storage Section with detailed example.

WORKING-STORAGE SECTION defines the data names that are needed for processing of data in the program.

WORKING-STORAGE SECTION also defines data items and general variables which might initialized either at the definition or during the program flow.

WORKING-STORAGE SECTION fields defined for internal usage in the program and cann’t be accessed outside of the program.

All the WORKING-STORAGE SECTION fields initialized at the starting of program execution.

Memory allocated to all WORKING-STORAGE SECTION fields when the program execution starts and gets deallocated when the program execution ends.

The WORKING-STORAGE SECTION must begin with the section header WORKING-STORAGE SECTION and followed by a separator period.

WORKING-STORAGE SECTION defines the records (record-description-entries) that are not part of file definition but still used to write into the file.

WORKING-STORAGE section can define individual, elementary and group data items (data-item-description-entries).
