ok let me tell it more clearly ..lets say I have a file a.txt
I am attempting to find if on any line I DO NOT have either 01,03,05,07,10 or 11 in position 9th or 10th.
if you look at record 2 above it as "33" in 9th and 10th position which is not in my list right? similarly if you look at record 9 ,it also

other than these two all records meet my criteria.
so in this case i want the sed to produce an output as follows which are the voilating lines:
------------------------------------------------------------------
lets take another example .. lets say my file a.txt contains
in this case all of the records match my criteira so sed should output nothing
cand you modify my sed command to achieve this ?
