Set the DIALECT“RM” Compiler Directive for the Project

Set the DIALECT"RM" directive in the project's properties so that it applies to all programs within the project unless you explicitly override it at the program level.

Right-click your project in the COBOL Explorer view and select Properties.
The Properties for <project-name> dialog box appears.
Select Micro Focus > Project Settings > COBOL.
The COBOL settings appear in the right-hand pane.
Set Language Dialect to RM/COBOL.
Click Apply and Close.
The RM/COBOL dialect is applied to any program within the project, unless that program overrides it by setting the DIALECT directive explicitly within the source code.
