Use DLL to instruct the compiler to generate an object module that is enabled for dynamic link library (DLL) support.
DLL enablement is required if the program will be part of a DLL, will reference DLLs, or if the program contains object-oriented COBOL syntax such as INVOKE statements or class definitions.

DLL option syntax

Default is: NODLL

Abbreviations are: None

Link-edit considerations:

• COBOL programs that are compiled with the DLL option must be link-edited with the RENT and AMODE(31) link-edit options.
• NODLL instructs the compiler to generate an object module that is not enabled for DLL usage.
