What are workbook variables limited to in regards to their use?

Workbook variables are designed to exist only within the confines of the same workbook. This means that the scope of these variables is limited to the workbook in which they were created. When a variable is instantiated within a specific workbook, it cannot be accessed or shared with other workbooks. This encapsulation ensures that variables maintain their integrity and intended functionality without external interference or unintended consequences from other workbooks.

In practice, this allows for a more controlled environment where each workbook can operate independently, holding its own set of variables that are not influenced by or accessible from elsewhere. This design can help prevent conflicts and ensure that data integrity is maintained, making it a more reliable process for users working within a single workbook environment.
