Definitions of EMS Tokens in the Event Message
Header
ZEMS-TKN-SUPPRESS-
DISPLAY
(type Boolean; shared) if TRUE, tells the ViewPoint
application not to display the event message; ViewPoint
displays it if the token is either FALSE or missing.
Use this token in messages that report status or history
that is useful for analysis but normally meaningless to
operators. The token is also useful for suppressing a
message that reports only an action-completion event.
When ViewPoint receives such a message, with this
token TRUE, it also clears the associated action-
attention message from the display.
An event message with the SUPPRESS-DISPLAY token
set to TRUE is still formatted by the printing distributor,
so the message should have a format template
associated with it or still contain a text token.
ZEMS-TKN-CONTENT-
STANDARD
(type enum; shared) indicates the type of standard event.
Standard enumerated values are:
ZEMS-VAL-NULL (default)
ZEMS-VAL-TRANSIENT-FAULT
ZEMS-VAL-OBJECT-UNAVAILABLE
ZEMS-VAL-OBJECT-AVAILABLE
ZEMS-VAL-OTHER-STATE-CHANGE
ZEMS-VAL-ATTN-NEEDED
ZEMS-VAL-ATTN-COMPLETED
ZEMS-VAL-USAGE-THRESHOLD
If an event is one of the events defined in this standard,
this token must be present, and its value must be its
event type. If an event is not one of the standard events,
this token must not be present, or its value must be EMS-
VAL-NULL.
This token can co-exist with another type token, ZEMS-
TKN-CONTENT-USER.
