8.82 K (Display CCKD internal trace)

8.82.1 Function

The K command displays the internal CCKD trace entries. Because the default value for the CCKD trace
entries is set to zero, the trace must first be enabled by setting a trace entry value. This can be done
either with the system parameter or the console command "CCKD TRACE=n", where n specifies the
number of available trace entries and can be in the range of 1 to 200000.

Please note that the K command can produce a lot of messages depending on the available trace entries.
