Your DG Interactive COBOL source programs can contain:
In either case you must specify the DG Compiler directive when you submit such source programs to this COBOL system.
The chapter Data General Interactive COBOL V1.3 Syntax Support in your Language Reference contains the DG syntax which is not found in the standard Micro Focus COBOL language
Features which are syntactically the same as Micro Focus COBOL features but have different behavior at run time, are described in the following sections of this chapter. Unless you set the DG directive at the time the object code is produced, this syntax behaves in the standard Micro Focus COBOL manner, as documented in the Language Reference. You do not need to amend DG Interactive COBOL source programs which contain these features, but if you try to submit them to this COBOL system without setting the DG directive they might not behave as you expect.
