How about:-
Code:
awk ' { for(i=1; i<=NF; i++) { if(match($i,/-/)>0) gsub(/./,"O",$i); if(i==NF) printf "%s\n", $i; else printf "%s ", $i; } } ' tempfile

Code:
This one worked fine for my problem.
cat tempFile | sed -e "s/\-..............$/O00000000000000/g" > filea
cat filea | sed -e "s/.\-.............$/O00000000000000/g" > fileb
cat fileb | sed -e "s/..\-............$/O00000000000000/g" > filea
cat filea | sed -e "s/...\-...........$/O00000000000000/g" > fileb
cat fileb | sed -e "s/....\-..........$/O00000000000000/g" > filea
cat filea | sed -e "s/.....\-.........$/O00000000000000/g" > fileb
cat fileb | sed -e "s/......\-........$/O00000000000000/g" > filea
cat filea | sed -e "s/.......\-.......$/O00000000000000/g" > fileb

cat filea | sed -e "s/...........\-...$/O00000000000000/g" > fileb
cat fileb | sed -e "s/............\-..$/O00000000000000/g" > filea
cat filea | sed -e "s/.............\-.$/O00000000000000/g" > fileb
cat fileb | sed -e "s/..............\-$/O00000000000000/g" > revised_file.

This will also do the magic,
Code:
cat $FILE | sed -e "s/B.[0-9]*[\-][0-9]*$/O00000000000000/g" > Temp_File
