How to display backslashes from a command stored in a variable

I have a file list of Unix comands with backslashes and other special characters. I am reading it into a loop and running the commands. At present I have :

cat Udata

LineNum=1

while read line

do

echo

echo

echo "**********************************"

echo "Process $LineNum"

echo "Code is >> $line"

echo "Results are: "

echo

eval "$line"

(( LineNum++ ))

done < hmregraw

hmregraw is the file with the commands such as

grep '\tA.:' Udata

The \ is not printing and in eval it is trying to run

grep 'tA.:' Udata

which is wrong. The line being read into the while loop from hmregraw has the \ removed. How can I preserve those backslashes? Is there a way I can do this with out modifying the other departments or creating another duplicate file?

Thank You.
