WORKING-STORAGE SECTION
WORKING-STORAGE SECTION
- WORKING-STORAGE SECTION is one of the important sections under the DATA DIVISION.
- It defines all the variables and record structures required to process data in the program.
- It defines the variables' type and size and initializes them with values if needed for processing.
Points to Note -
- The variables are defined for internal usage in the program and can't be accessed outside.
- Memory is allocated to all WORKING-STORAGE SECTION variables when the program starts and is deallocated when it ends.
- It also defines the data record structures that are part of the file definition but are still used to perform file operations.
