# Enabling consistency with Tonic Structural

If you also use Tonic Structural, then you can configure Textual to enable selected synthesized values to be consistent between the two applications.

For example, a given source telephone number can produce the same replacement telephone number in both Structural and Textual.

To enable this consistency, you configure a statistics seed value as the value of the Textual [environment variable](/textual/textual-install-administer/configuring-textual/textual-env-var-configure.md) `SOLAR_STATISTICS_SEED`. A statistics seed is a signed 32-bit integer.

The value must match a [Structural statistics seed value](/app/generation/generators/generator-characteristics/consistency.md#enabling-consistency-across-runs-or-multiple-databases), either:

* The value of the Structural environment setting `TONIC_STATISTICS_SEED`.
* A statistics seed configured for an individual Structural workspace.

The current statistics seed value is displayed on the **System Settings** page.
