How to assign a varaible containg spaces to another variable in KSH

I am writing a shell script to read the input file and process the contents of the file line by line. I was planning to store each line to an array and process the array later as shown below.

#--------------------------------
# Global Variable
file_path="NULL"
set -A array_statements
#--------------------------------
readFileIntoArray()
{
    while IFS= read -r line
    do
        echo "$line"
        array_statements[${#array_statements[*]}+1]="$line"
    done <"$file_path"
}
printTheArray()
{
    for i in ${array_statements[@]}; do 
        echo $i
    done
}
main()
{
    file_path=$1
    readFileIntoArray
    printTheArray
}
main "$@"

The line contains spaces between the words as Hello World How Are You?. When I execute the script, and print the content of the array_statements, the output is 

Hello
World
How
Are
You?

How do I assign the variable value which contains spaces to another variable or pass the varaible which contains spaces to another function in KSH.

Thanks

The easiest route forward is probably to scrap your current code and refactor it.

array_statements=()
while read -r line; do
    array_statements+=("$line")
done <"$1"
printf "%s\n" "${array_statements[@]}"

With the code simplified this much, it probably doesn't make much sense to keep anything encapsulated in a separate function.

Notice in particular how missing the quotes around ${array_statements[@]} will break them up into one happy crazy string, losing any array element boundaries.
