# Description
Use the buildNumber function to determine which engine version the application is using. This is useful to figure out, for example, whether a certain LiveCode feature is available.
The buildNumber of two copies of LiveCode or a standalone application may be different, even if the version function returns the same number. This is because new builds of the same version may be released to provide fixes to specific problems.
When reporting a problem with LiveCode, please include the buildNumber and version of the application.
