RM/COBOL Data Types

When you compile your programs with the DIALECT"RM" Compiler directive, all data types behave in the same way that they do in RM/COBOL.

If you do not compile with the DIALECT directive, you can still preserve RM/COBOL behavior for certain data types by using certain other Compiler directives: COMP, COMP1, COMP2, and COMP-6.
