z/OS Language Environment Debugging Guide supports z/OS (5694–A01). It contains information to help you detect, find, and fix programming errors that occur during run time under Language Environment. It can help you establish a debugging process to analyze data and narrow the scope and location of where an error might have occurred. You can read about how to prepare a routine for debugging, how to classify errors, and how to use the debugging facilities Language Environment provides. Also included are chapters on debugging HLL-specific routines and routines that run under CICS®. Debugging for AMODE 64 applications is also provided.
