Format Model Processor Service

The format model processor service formats and prints an entire control block using a control block model. If a model name is specified, the service loads the model. If a dump address is specified instead of a buffer address, the service accesses the storage, using either the length indicated in the model or the value in ADPLPBLS, if it is not zero.

The maximum size of the control block is 64 kilobytes

You can create your own model by using the BLSQMDEF, BLSQMFLD and BLSQSHDR macros. These macros allow you to tailor your requested control block's output.

You can extend the capabilities of the format model processor service by writing a model processor formatting (MPF) exit routine.
