You must have altered IFS somewhere, since that string isn't even splitting while unquoted.

Yes, I am using IFS at an earlier place and it is very much required there. The below piece of code shows that.

Code:
 
IFS=' '
while read -r dir; do
(
        cd $dir
        files2del=$(find ./ -type d ! -name . -prune -o -mtime +$NUM_DAYS -name '*.dat' )
        echo "$files2del"
for i in $files2del
                do
                        echo "Arg is ="
                done
)
done < dirlist_1.txt

Could you please advise how do I get the for loop correct.

You can just specify IFS for the read instead of changing it for the entire program:

Code:
while IFS=" " read -r dir; do
(
        cd $dir
        files2del=$(find ./ -type d ! -name . -prune -o -mtime +$NUM_DAYS -name '*.dat' )
        echo "$files2del"
for i in $files2del
                do
                        echo "Arg is ="
                done
)
done < dirlist_1.txt

This should let $files2del split on any whitespace.

But really, you shouldn't be putting an open-ended list like that into a variable. I don't think you need to cd either.

Code:
while IFS=" " read -r dir
do
        find "$dir" -type d ! -name . -prune -o -mtime +$NUM_DAYS -name '*.dat' | while read i
        do
                echo "got file $i"
        done
done < dirlist_1.txt

Or even just:

Code:
while IFS=" " read -r dir
do
        find "$dir" -type d ! -name . -prune -o -mtime +$NUM_DAYS -name '*.dat' -exec command_to_run_for_each_file '+'
done < dirlist_1.txt
