## Description
Variables declarations should be ordered by type. In general, object and complex variable types are listed first followed by simple variables. The order should be:

- Record
- Report
- Codeunit
- XmlPort
- Page
- Query
- Notification
- BigText
- DateFormula
- RecordId
- RecordRef
- FieldRef
- FilterPageBuilder
