Current revision number of the VI.

When writing this property, you can write only a value greater than the current revision number. If you attempt to write a revision number whose value is less than the current revision number, the property returns an error. Use the Clear History method to reset the revision history and the revision number.

This property is similar to the Next Revision option in the History window.
