The debugger can debug executable programs (EXE) and dynamic link libraries (DLL) called from executable programs. This chapter refers to these executable programs and dynamic link libraries as debug target programs.
Usually, a debug target program consists of multiple COBOL source programs. For the debugger to recognize one of these programs for debugging, you need to create a debugging information file by compiling with the TEST option. Since the debugger maintains user resource compatibility, you can use it without having to recompile and re-link old resources.
