  • INITIALIZE verb: As name suggests, it is used to initialize an elementary item or a group item. It functions similar to VALUE clause. The difference is that VALUE can be used to initialize data item in WORKING-STORAGE SECTION and thus initialization in this case takes place only at the beginning of the program execution. Whereas, INITIALIZE can be used to initialize data item as and when necessary in PROCEDURE DIVISION. For more details about INITIALIZE verb, click here
