If I judge correctly, you have gotten a long ways into the INSTEP4,
but with just a small fragment it is hard to tell what is wrong.  Did
all areas prior to $APGNOT compile and link correctly?  INSTEP4 stops
at the end of an area that does not link fully (or at least it is
supposed to).

What programs did not link in $APGNOT and what subroutines are missing
in them?

The few lines before this would show me what library tree your linker
is using and - if that is wrong - why it is failing.

This is meaningless for the moment.  The new OS wants us to use
updated routines but the old compiler provides old ones.  The new
compiler does not work well (see aips web page).

     NXREAD is a routine in VLOG and references correctly TABNDX in
the $APLNOT area

     CHNDAT is in $APLNOT and references correctly TABFQ in the
$APLNOT area.

     Check your INSTEP2 for $APLNOT and these 2 subroutines.  It seems
odd to me that 3 routines beginning with TAB are all missing.

     cd $LIBR/APLNOT
     ar -t SUBLIB | grep TAB

to see if these routines are present in the library.
