:::info Backwards Compatibility
This function replaces [system.gui.getScreenIndex](versioned_docs/version-8.1/appendix/scripting-functions/system-gui/system-gui-getScreenIndex.md). Any scripts containing Vision Client scoped functions that were replaced with system.vision syntax will still work to maintain backwards compatibility.
