Rick,
Because a GUID uses the MAC address of the primary network adapter to make sure its unique, you can create a GUID and parse it for the MAC address.

clear
local lcguid
lcguid = GetGUID()
return substr(lcguid,26,2)+'-'+substr(lcguid,28,2)+'-'+substr(lcguid,30,2);
	+'-'+substr(lcguid,32,2)+'-'+substr(lcguid,34,2)+'-'+substr(lcguid,36,2)

function GetGUID
local lcStrucGUID, lcGUID, lnsize
declare integer CoCreateGuid in Ole32.dll string @lcGUIDStruc
declare integer StringFromGUID2 in Ole32.dll string lcGUIDStruc, string @lcGUID, long lnSize

lcStrucGUID=space(16)
lcGUID=space(80)
lnSize=40

if CoCreateGuid(@lcStrucGUID) # 0 then
   return ""
endif
if StringFromGUID2(lcStrucGUID,@lcGuid,lnSize) = 0 then
  return ""
endif
return strconv(left(lcGUID,76),6)

GetGUID code was posted by John Koziol (who I believe got it from Rick Strahl) here last year.

HTH.
