Event message formats

Event logging message formats correlate closely with event actions. There are six distinct formats.

Contents
  • Format 1: event occurs
  • Format 2: indirect action
  • Format 3: pushed on to the stack/popped off the stack
  • Format 4: generated by the ABL APPLY statement
  • Format 5: trigger execution
  • Format 6: event discarded
