>I am using the command OS(1) to return which version of windows is currently running on a system. It returns "Windows 5.01" (this i guess means WinXP cause thats what I am using). I need to determine what the different values that get returned mean for example is windows 4.01 = WINDOWS ME ? is windows 2.01 = Windows 98 ? Help!?!?
>Also on a simular subject how do you know which Windows Service pack is installed?


Another way you can do it is Using WMI, if you have any of this OSs:

Client: Included in Windows XP, Windows 2000 Professional, Windows NT Workstation 4.0 SP4 and later.
Server: Included in Windows Server 2003, Windows 2000 Server, Windows NT Server 4.0 SP4 and later.

? getOSVersion()

function getOSVersion()
local loWMIService, loWBEMLocator, loOSs, loOS, lcOSVersion


lcOSVersion	= 'Unknown'

try
	loWBEMLocator	= createObject("wbemScripting.SwbemLocator")
	loWMIService	= loWBEMLocator.ConnectServer()
catch
	loWMIService	= null
endtry

if not Isnull(loWMIService)
	loOSs		= loWMIService.ExecQuery('Select Caption, Version, ServicePackMajorVersion, ServicePackMinorVersion from Win32_OperatingSystem')
	for each loOS in loOSs
		with loOS
			lcOSVersion	= .Caption + " " + .Version + " SP " + Transform(.ServicePackMajorVersion) + '.' + Transform(.ServicePackMinorVersion)
		endwith
		exit
	endfor
endif
return lcOSVersion

You can add/or remove information from the final string, or change the format or whatever
