Because of the unique nature of the Windows environment, Windows developers have the ability to include ActiveX and OLE objects in their ACUCOBOL-GT program. ACUCOBOL-GT comes with a utility called "AXDEFGEN" that generates COBOL copybooks for any ActiveX or OLE object registered on the developer's system. Then ACUCOBOL-GT compiler then uses these copybooks for syntax and parameter type checking as well as efficient code generation. For specific information on "ActiveX and OLE Programming," please refer to section 6.10 in Book 1, "User's Guide."
