Sheet Preamble

A preamble is the section at the beginning of each RVL sheet that contains common data definitions.

The preamble is executed every time you use Play Selection or Play From Here in RVL. This means that if a selection refers to any Variables, Repositories, or Maps from the preamble, the executed statement will recognize them as if they were part of the selection.

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

For example, the preamble here ends on row 10 because row 11 contains an Action.
