=HPER
This diagnostic command sets one or more break-points for a list of named modules and
offsets. The CP QUERY PER command is then issued to display the current program traps
in effect.
Note: In the VM/XA environment, CP PER and QUERY PER are synonyms for the CP
TRACE and QUERY TRACE commands.
‘CP SET RUN OFF’ is executed, and the SCP debug environment is entered. The
diagnostic command ‘=NODEBUG’ terminates the debug environment.
=
the command character for the DIAG subsystem. The default is ‘‘=,’’ but may be set
to any character by the SUBSYS command that started the subsystem.
epname
the name of a known entry point. It is either named in the map within any
SLKNUCxx module or there is a CDE structure for the name.
If the name is known, it will be located in storage. It will be brought into storage if it
was not there before.
If epname is not specified, the current traces are displayed.
offset
the optional offset from the address of epname at which to set a breakpoint using CP
PER. The default is 0.
.length
the optional length of the breakpoint. The default is .1.
Note: length must be preceded by a period with no space between offset and the
period.
For example, issuing the command:
=HPER slsbinit slkode 54.8
