This is the entire code I have tried.<pre>
DECLARE Integer WNetAddConnection IN WIN32API STRING @, STRING @, STRING @

lcRemoteName = "\\R6Vabs\Vol1\OraApps\OraWin95\Bin" + chr(0)
lcPassword = ""    && Connect using no password, already authenticated
lcLocalName = "I:" + chr(0)

lnRetVal = WNetAddConnection( @lcRemoteName, @lcPassword, @lcLocalName)

*-- lnRetVal is 0 and I can verify that I: now exists to the path specified

DECLARE SHORT SetEnvironmentVariable IN Win32API;
   STRING @lpname, STRING @lpszValue
lcName = 'PATH'
lcPath = getenv("PATH") + ";I:." + Chr(0)
lnRresult = SetEnvironmentVariable(@lcname, @lcpath)
clear
?
?
? getenv("PATH")    && still shows old path
return

At the end of the rope at this point.
