Format of the message body
The message body consists of three parts: the reply identifier (optional), the message identifier, and the message text. The following formats are possible:
id CCCnnn text
id CCCnnns text
id CCCnnnns text
id CCCnnnnns text
id CCCSnnns text
- id
- Reply identifier: It is optional. It appears if an operator reply is required. The operator specifies it in the reply.
- CCCnnn, CCCnnns, CCCnnnns, CCCnnnnns, CCCSnnns
- Message identifier.
- CCC
- A prefix to identify the component, subsystem, or product that produced the message. The prefix is three characters.
- S
- The subcomponent identifier, which is an optional addition to the prefix to identify the subcomponent that produced the message. The subcomponent identifier is one character.
- nnn, nnnn, nnnnn
- A serial number to identify the individual message. The serial number is three, four, or five decimal digits.
- s
- An optional type code, which is one of the following:
- A
- Immediate Action: System operator action is always immediately required. A
system operator must do something now, such as mount a tape cartridge or attach a DASD.
The associated task does not continue until the requested action has been taken.
- D
- Immediate Decision: System operator decision/action is always immediately required. All
system messages issuing the “D” type code must enumerate the available options. A system operator
must make a decision now by selecting a reply from the enumerated options and responding to the
system immediately.
The associated task does not continue until the operator communicates the decision to the system.
- E
- Eventual action: System operator action will be required. A system operator must
eventually an appropriate action.
The associated task continues independent of system operator action.
- I
- Information: System operator action is not required. Communication in this category is
for advisory purposes and may provoke system operator action.
The associated task continues independent of system operator action.
- S
- Severe error: Severe error messages are for a system programmer.
- T
- Terminate: The IEBCOPY program terminates.
- W
- System Wait: System operator action is always required immediately. A system catastrophe has occurred (hardware or software or both). The system must be re-IPLed to continue or a major subsystem must be re-started.
- text
- Text: The text provides information, describes an error, or requests an operator action.
