6.1 Procedure Division Structure
X The Procedure Division is optional in a COBOL source program, class
X definition, and method definition.
- Program Procedure Division
-
A program Procedure Division consists of optional declaratives, and
procedures that contain sections and/or paragraphs, sentences, and
statements.
-
X Class Procedure Division -
X The class Procedure Division contains only method definitions. All
X methods introduced in a COBOL class compilation unit must be defined
X in that compilation unit's Procedure Division. -
X Method Procedure Division -
X A method Procedure Division consists of optional declaratives, and
X procedures that contain sections and/or paragraphs, sentences, and
X statements. A method can INVOKE other methods, be recursively
X INVOKEd, and issue a CALL to a program. A method Procedure Division
X cannot contain nested programs or methods.
X For additional details on a method Procedure Division, see
X "Requirements for a Method Procedure Division" in topic 6.1.1.
