Debugging a LangX COBOL program

You can use most of the z/OS® Debugger commands to debug LangX COBOL programs that have debug information available. Any exceptions are noted in IBM® z/OS Debugger Reference and Messages. Before debugging a LangX COBOL program, prepare your program as described in Preparing a LangX COBOL program.

As you read through the information in this document, remember that OS/VS COBOL programs are non-Language Environment® programs, even though you might have used Language Environment libraries to link and run your program.

VS COBOL II programs are non-Language Environment programs when you link them with the non-Language Environment library. VS COBOL II programs are Language Environment programs when you link them with the Language Environment library.

Enterprise COBOL programs are always Language Environment programs. Note that COBOL DLL's cannot be debugged as LangX COBOL programs.

Read the information regarding non-Language Environment programs for instructions on how to start z/OS Debugger and debug non-Language Environment COBOL programs, unless information specific to LangX COBOL is provided.
