To display a CTE, you can use a model, which is a template. For most CTEs, usually only a model is needed, rather than a formatter or formatter and model.

In the CTRACE format table, specify a model by either a name or address on the MODELNAME or MODELADDR parameter of the ITTFMTB macro. Use MODELADDR when the model resides in the same load module as the CTRACE format table. Use MODELNAME when the model does not reside in the same load module as the CTRACE format table. The model must reside in a load library available to IPCS. See Making Load Libraries Available to IPCS for how to make a load library available to IPCS.

When a model is specified by name in the format table, CTRACE loads it and retains its entry point for subsequent use. All such loaded support is deleted when CTRACE completes.

If the model for a particular format ID key (CTEFMTID in the ITTCTE mapping macro) is a model, IPCS calls the model processor service specifying that model and the appropriate view control value from the table.
