Action codes

Certain messages (for example, DFHDB8208D) include an action code after the message identifier. Action codes give guidance to the operator of the type of action needed when the message appears on the system console.

The following action codes are used:
A
Immediate action; for example, mount a tape.
D
Immediate decision; reply to a request, for example, enter GO or CANCEL.
E
Eventual; action is required, but does not have to be taken immediately.
I
No action required. If issued by the message domain, these messages can be suppressed by specifying MSGLVL=0 as a system initialization override.
