There are a couple of ways. Easiest would be to use the WScript.Network object of the Windows Script Host.

oNet = CREATEOBJECT("WScript.Network")
? oNet.UserName

Now if the WSH isn't available...

DECLARE INTEGER WNetGetUser IN Win32API;
  STRING @lpszLocalName, STRING @lpszUserName,; 
  INTEGER @lpcchBuffer
LOCAL lcresult, lnpt, lnargs
* Call to the API
lcresult = SPACE(200)
= WNetGetUser(0, @lcresult, LEN(lcresult)) 
lnpt = AT(CHR(0), lcresult)
IF lnpt > 1
  lcresult = LEFT(lcresult, lnpt - 1)
ELSE
  lcresult = ""
ENDIF
