(Total time is one example. "OnLoad" type events in GUI programming are
another.)

Event-driven doesn't necessarily mean "it can happen at any time, in no
specific order." It depends on the nature of the event. Some events
occur at very specific predictable times. (Total time is one example.
"OnLoad" type events in GUI programming are another.)

Some events can happen at any time, as you say. ("OnClick" type events
are an example. These are less common in RPG... but database triggers,
signal handlers, CEEUTX events, CEE4RAGE events are all event handlers
that I've coded in RPG. A more commonplace one might arguably be *PSSR.
But, again, this type of event handling is not commonplace in RPG, and
if you really think about why, it's because other environments primarily
do it for GUI events. Note when I say "primarily", I mean MOST of the
time, not all the of time.)

Gerald Weinberg, in his tome on Systems Design (forget the exact title)
observed that "In most systems most of the time nothing is happening at
all."
