Comments:

The MO:DCA header allows the storage of multiple IOCA images in one file. The MO:DCA format is an IOCA "wrapper". It is considered by IBM to be a "data stream controlling environment" for a group of IOCA images.

There are many optional parameters. Subsets of IOCA parameters are referred to as "function sets" and define different flavors of the IOCA, for example, the MO:DCA. The MO:DCA incorporates function sets "10" and "11".

Please see the description of IBM IOCA in this chapter for further description.
