Sheet Preamble

Preamble is a beginning of each RVL sheet containing common data definitions.

Preamble is executed every time when one does Play Selection or Play From Here in RVL. So if the piece that you try to have executed refers Variables, Repositories or Maps then executed statement will 'see' them as if they are part of the selection.

The preamble is detected automatically. Everything before first Action, Assertion, Loop or Condition is a preamble.

For example, Preamble here ends at the row 10 (because row 11 is Action)
