The CODE Clause
The CODE clause specifies a two-character literal that identifies each print
line as belonging to a specific report.
General Format

Syntax Rules
- Literal-1 must be a two-character nonnumeric literal.
Literal-1 may be replaced by a mnemonic-name specified in the special-names
paragraph. See the OS/VS COBOL Language Reference for additional details.
- If the CODE clause is specified for any report in a file, it must be specified
for all reports in that file.
General Rules
- When the CODE clause is specified, literal-1 is automatically placed in the
first two character positions of each report writer logical record.
- The positions occupied by literal-1 are not included in the description of
the print line, but are included in the logical record size.
