The purpose of this call is to enable an event.
This call enables a particular event so that it is being called through the EventV (event vector). A count is maintained of the number of enables and disables set so that multiple routines enabling and disabling events are handled correctly.
An event will only be disabled after equal numbers of disable events and enable event calls have been made.
