Report Files and RD Entries
This part contains full information about the COBOL-IT Report Writer elements that can appear in the ENVIRONMENT DIVISION and FILE SECTION of your program, and then, in alphabetic order, the clauses that may be used in an RD entry.
If you are migrating older programs written using OS/VS or DOS/VS COBOL's built-in Report Writer, you should refer to the Compatibility paragraph at the end of each section, which points out any new Report Writer features that these compilers do not accept.
Although most of the examples that follow use UPPER-CASE text, you may also use lower-case characters in any of the keywords and operands.
