Enterprise COBOL compiler can't create an unnamed CSECT.
How to make the compiler generate a Control Section that has no name? The Binder can handle $PRIVATE names.
Starting with z/OS V1R13 the Program Management Binder supports new operations for unnamed ($PRIVATE) sections in load modules and program objects.
Diagnosing the problem
The C compiler can do this using its NOCSECT option. Assembler language programmers can do this by omitting the CSECT statement.
Resolving the problem
This feature is not available in Enterprise COBOL for z/OS.
