Uninstall script – reboot syntax

I am trying to use an uninstall script with the Symantec packager to first uninstall Innoculan before installing Symantec Anti-Virus. Innoculan requires a reboot after the uninstall is complete prior to installing SAV. Does anyone know what syntax to use in the uninstall script to automate the re-boot for BOTH Windows 95 and Windows 98?

Thank you.
