Returns a string to identify the operating system and version. The first word of the returned string contains the identifier for the operating system and the rest of the string contains a operating specific version string. Something like: WindowsNT x or Linux x.

Some possible output for operating systems supported by ooRexx might be:

Say SysVersion()   ->  "Linux #1 SMP Mon Oct 16 14:54:20 EDT 2006.2.6.18-1.2798.fc6"
Say SysVersion()   ->  "WindowsNT 5.00"

Note: This function can be used to replace the operating-system-specific functions SysWinVer(), and SysLinVer().
