Event Messages
This section describes the contents and meaning of all event messages defined by 
OSI/MHS. OSI/MHS also generates event messages defined by ZCMK and ZCOM. 
For descriptions of ZCMK-defined and ZCOM-defined event messages, see the 
SPI Common Extensions Manual.
Within the OSI/MHS subsystem, the MHS manager and TAPS processes generate event 
messages. All event messages generated by these processes contain the OSI/MHS 
subsystem ID, which is described under SPI Standard Definitions
 on page 4-2.
In this section, command numbers, object types, and all tokens and their values are 
represented in Data Definition Language (DDL).  For a quick explanation of DDL, see 
the SPI Programming Manual.
Table 6-1
 lists the OSI/MHS event messages in order by name. The descriptions in this 
section are listed in order by event number. The ellipses in the table represent variable 
text.
