E732 Enterprise PL/I Debugging and Maintenance

Course Code: E-732
Recommended Duration: 2 Days

Benefits

The student will learn to approach debugging systematically, using the appropriate features of the PL/I language to facilitate debugging. In addition, he or she will learn to interpret the various forms of debugging output from PL/I, including CEEDUMPs.
