Division Header
A division header is a combination of words, followed by a separator period, that indicates the beginning of a division:
- IDENTIFICATION DIVISION.
- ENVIRONMENT DIVISION.
- DATA DIVISION.
- PROCEDURE DIVISION.
A division header (except when a USING phrase is specified with a Procedure Division header) must be immediately followed by a separator period. Except for the USING phrase, no text may appear on the same line.
