Hi netters

I have a problem with the IRC in Gaussian 98
The manual says that the option DOWNHILL follow the reaction path downhill from a starting point that is not a transition state. But this is not correct, because this option is not accepted by the program:

****************************************************************************************************
 TestRt Revision:  G98A.9
 Please type in the route specification, terminated with a blank line:
#n rhf/6-31g irc=downhill

 -------------------------
 #n rhf/6-31g irc=downhill
 -------------------------
  QPERR --- A SYNTAX ERROR WAS DETECTED IN THE INPUT LINE.
 #N RHF/6-31G IRC=DOWNHILL
                               '
 Last state="IRC1"
 TCursr= 9814 LCursr=  17
 Error termination via Lnk1e
***************************************************************************************

The option 'downhill' gives a syntax error !!

What happens??

Thanks in advance
