The system selected module IEANUC0X as the base
nucleus module to load into the DAT-on nucleus region. (DAT is the
acronym for dynamic address translation.) The system issues this message
so that the operator can verify the nucleus selected.
In the
message text: x

System action
The initial program load (IPL) program loads IEANUC0x into
the DAT-on nucleus region.
