Using the IHABLDP Macro

The IHABLDP macro builds a parameter list to be passed as input to the SDUMPX macro. SDUMPX allows you to request structure information from a coupling facility

You build the parameter list by multiple invocations of the IHABLDP macro. For each structure that you specify in the parameter list:

You can specify that you want a range of information (for example, a range of cast-out classes for a cache structure), or
You can specify that you want specific options included (such as the lock table entries associated with a list structure).

You begin building the parameter list with the TYPE=INITIAL parameter; you end its construction with the TYPE=ENDLIST parameter. The parameter list is mapped by the IHASDSTR macro.

The size of the area in which you build the parameter list depends on the amount of structure information requested. For the best utilization of space within the parameter list, you should group all the range and option requests for a single structure together. The information for each structure will be dumped in the order it is specified in the parameter list.

Once the parameter list is built, you can specify it as input to SVC Dump by specifying its address on the SDUMPX STRLIST keyword.
