EGEN Default Values
EGEN Default Values
EGEN default values are used by the EGEN procedure to determine if information
should be added to the event buffer. EGEN compares the value of each field defined in
your ACF against a set of default values. Each field type supported by EGEN has a
specific default value.
Before generating an event, an application always initializes all fields of the egen-record
(the egen-record contains all the fields declared in the ACF) with default values. This is
done with the initialize^egen^record procedure. The following values are entered into
the field types:
These default values were assigned because they represent values which are unlikely to
occur during the course of running an application. If the actual value passed to EGEN
differs from the default value, that new value is passed to the event message buffer. If the
actual value matches the default value, EGEN assumes nothing has changed, and no
value is added to the event buffer. The objective is to supply information which does not
match the default values. If you feel that one of the EGEN default values may in fact
match a legitimate value passed by an event, change the default value for that field type.
If you do not do this, variable data will be missing from your event message buffer.

Table 6-4 shows the contents of the following fields after a call to the
initialize^egen^record procedure.
