Chapter 2 Program Structure 

COBOL is similar to the English language in both structure and content.
Structurally, for example, COBOL programs are made up of such familiar
constructs as paragraphs, sentences, statements, and clauses. These
constructs, in turn, contain such elements as words, names, verbs, and
symbols. Program constructs are described in this chapter of the manual;
program elements are described in Chapter 3 .

Within the context of COBOL, constructs and elements all have very
specific meanings. In this manual, all such terms are defined at or near
the point where they are introduced. For additional convenience, their
definitions appear in the glossary in Appendix E .

The concept of program modules is also described in this chapter. These
modules make up a superset into which all other constructs fall; they
contain almost all of the program constructs.
