Debugging Native COBOL Link Libraries

You can directly debug Link Library projects that produce a single .dll file. The entry point for this type of projects is always the first COBOL program passed to the linker when the .dll is created, or the program which you may have specified in your own .def file. If you do not use a .def file, the IDE links programs in the order in which they appear in the project file which is alphabetical order by default.

Restriction: You cannot directly debug native Link Library projects which produce multiple .dll files (each COBOL program in the project compiles to a separate .dll file). Instead, you must specify one of the output .dll files (or an executable which loads it) in the "Start external program" option on the Debug tab in your project properties.
