This course is designed to provide students with the skills to use Xpediter to test and debug COBOL programs. Students will test, analyze and debug COBOL programs using Xpediter running under TSO.
Upon completion, students will be able to set breakpoints, view and modify data fields, step through program logic, temporarily change program logic, set WHEN conditions, monitor execution path of a program, detect and correct abends as they occur, and test subprogram modules. In addition, they will know the requirements for preparing for an Xpediter session and the purpose and function of the repository.
