COBOL: INITIALIZE Vs FILLER. After the execution of INITIALIZE statement, variables RPT-EMP-NAME & RPT-EMP-NO will be initialized to SPACES. But the FILLER will retain the value 'I AM A FILLER'. Hence we conclude that the INITIALIZE verb cannot initialize FILLERs.

Regarding this, how do you use FILLERs in Cobol?

You use FILLER immediately following a level number and preceding a PICTURE clause that defines a field's size and data type. COBOL restricts the use of FILLER to the Data Division; it does not apply to the Identification, Environment or Procedure divisions.

What is dynamic array in Cobol?

Re: Dynamic Array Strictly, Cobol does not have Arrays. It has Tables. A Table which uses Occurs Depending On is defined in the program by the Compiler has using the storage for the maxium value of the OCCURS specified. There is nothing "dynamic" about it in the sense that other languages use that word.

What is Cobol copybook example?

A COBOL copybook is a selection of code that defines data structures.

COPY statement is used in the WorkingStorage Section.
