IUCV Interrupt Buffer
As an IUCV-type external interrupt occurs, CP places data in the IUCV external interrupt 
buffer. The data describes the type of IUCV event, and data specific to each event subtype. 
For a full description, see the appropriate VM documentation. 
The external interrupt is traced in the internal trace table, and the first 8 bytes of the 
IPARML are saved in the TTE. 
The following is a list of possible IUCV interrupt codes.
