Source code errors in initial distribution of nbo_59.src source file
(prior to October 13, 2009):

1.  In line 30270, delete reference to variable KOPT (the only
    such reference in the file) from COMMON/NBOPT/.  The corrected
    form of the common block (lines 30269-30271) should read:

      COMMON/NBOPT/IWDM,IW3C,IWAPOL,IWHYBS,IWPNAO,IWTNAO,IWTNAB,
     + IWTNBO,IWFOCK,IWCUBF,IPSEUD,IPRINT,IWDETL,IWMULP,ICHOOS,
     + IWNBBP,IWMSP,IWFIXDM,IW3CHB,IWNJC,JCORE,JPRINT(100)

2.  In lines 43812 and 43818, the first character of each line
    should be a star ('*') rather than a blank (' ').  The
    corrected form of line 43812 is

*       CALL ACLEAR(NATOMX,RNFROZ)                                      G09DRV

    and that of line 43818 is

*       IF(RNFROZ(I).NE.ZERO) IPSEUD = 1                                G09DRV

Note that these corrections were incorporated in all NBO 5.9 orders
completed after October 13, 2009.
