Script executed when?

[polymemnon]

The CM Help file says about the script loop: "This loop is executed periodically depending on several factors, whether and (sic) real data has changed, how long it's been since the last pass through the loop, etc."

Specifically, what "real data" triggers the script? Does this include changes to CURRENTMODE, PROTHRMODE, etc.?

And what is the maximum time interval between script executions?
