I wonder if there is a simple way to flag a change in input etc. other than setting a flag at every script.

Typically this would be where a value is changed by the user, a "recalculate" or "save" or some other process must follow so the user does not overlook the requirement.

I suspect the change in the field triggers a message in REV, if so, how can this be utilised (a code snippet would be great)
I am sure most developers have solved this and newbies would benefit from the tip.

I would!

For fields, you can always handle the closeField message, which is sent when the user has changed the content of a field and leaves it (by tabbing out of it or clicking on another field) - but this doesn't help when the text is changed by a script, so you'll still have to set the flag yourself from there.

Also check out the "exitField" message, sent when the user leaves the field, but when nothing has changed.
