Bill,

I'd assume it would be because the environment variable wasn't/isn't set in XP. The GETENV() function maps to an API call named GetEnvironmentVariable(). To test this theory, you could try the following

DECLARE INTEGER GetEnvironmentVariable IN Win32API;
  STRING @lpName, STRING @lpBuffer, INTEGER nSize
lcname = 'WINDIR'
lnsize = 260
lcbuffer = SPACE(lnsize)
lnsize = GetEnvironmentVariable(@lcname, @lcbuffer, lnsize)
IF lnsize > 0
  ? LEFT(lcbuffer, lnsize)
ELSE
  ? lcname + " not found!"
ENDIF
