$GRAD group   (relevant for RUNTYP=OPTIMIZE or SADPOINT)                        
           (relevant for RUNTYP=HESSIAN when RDHESS=.TRUE.)                     
                                                                                
    Formatted gradient vector at the $DATA geometry.  This                      
data is read in the same format it was punched out.                             
                                                                                
    For RUNTYP=HESSIAN, this information is used to                             
determine if you are at a stationary point, and possibly                        
for projection.  If omitted, the program pretends the                           
gradient is zero, and otherwise proceeds normally.                              
                                                                                
    For geometry searches, this information (if known) can                      
be read into the program so that the first step can be                          
taken instantly.
