Setting up the link list data set (SEQAMOD)

The hlq.SEQAMOD data set must be in the load module search path whenever you debug a program with z/OS® Debugger.

Unless you put hlq.SEQAMOD in the system link list concatenation, the user will have to alter the execution environment of any program being debugged so that hlq.SEQAMOD is in the load module search path (such as placing it in JOBLIB, STEPLIB, ISPLLIB or via use of TSOLIB). Therefore, it is recommended that you add the hlq.SEQAMOD data set to the system link list concatenation¹.

hlq.SEQAMOD must be placed before any other library in the load module search path that contains CEEEVDBG for z/OS Debugger to get control of a debug session.
