This variable is used to initialize the SpecialBuild string in the VERSIONINFO resource of the installation package. Because InstallMate allows any variable to be set on its command line during batch builds, this allows you to embed custom information (for example, a serial number) in your installers.
Note: By default, this variable is not saved in the installation database. If you want to use its value elsewhere in the project, you should check its Include in installer box in the Symbolic Variable attributes pane. If you fail to do so, InstallMate will issue a BLD:W0103 diagnostic when you build the project.
You can refer to it as <SpecialBuild>. Set this variable if you want to store a value in the VERSIONINFO SpecialBuild string. The maximum length for this string is 64 characters.
