Data and Datafile Definitions in COBOL
The COBOL Data and Datafile Definitions course explains how the COBOL programming language describes and defines data. It also shows how COBOL data definitions can be used to manipulate the way data is used. It explores display and computational formats, and the use of redefines to reference data in different ways.
Entry-level Programmers requiring an understanding of how COBOL handles data.
