The main group for followup to this is: comp.unix.shell.
I hope that I have the relevant groups for cross-posting.

Even though the problem posed in this thread is still

*** UNSOLVED ***

let me extend my gratitude to Mr Dragan and Mr Yuan
for their kind attempts to answer this. I hope that
someone is able to put more helpful replies tonight.

Mr Dragan's reply of grep+tr is actually misleading
as concurred by Mr Yuan.

Dr Yuan's reply uses perl which is not familar to me
and I would appreciate a solution that is based on
bash, sed and awk since that is what I can take and
modify at this time.

Note, I CAN write a wrapper loop in bash and I just need
proof of concept for one file processing in this fashion

cat file |
sed or awk |
sed or awk |

and so on.

However, since we are making a replacement within a
pattern, I do not think only grep+tr would help. I would work
to understand a sed solution even if involves shuttling
back and forth data from the pattern space to the
holding space.

Thanks a lot and do not forget to have fun working on
this problem. It is a little out of the way.
