store the generated output into variables in shell scripting -

how store output generated curl request variables

m=$(curl  -b cookiez.txt -l http://bmcassistant.org/webac/department/student/currentsemesterdetails.aspx?|grep -o 'href=.*>.*%' | grep -o '>.*%'|sed 's/>//')   echo $m>>attendance.txt 

output of attendance.txt

10% 80% 50% 100%

i want store these numbers variables m,n,o,p can call later in shell script referencing them $m,$n,$o,$p

i think should trick:

while ifs='' read -r line || [[ -n "$line" ]];   read -a arr <<< $line   echo ${arr[@]} done < "attendance.txt" 

change @ different values.

instead of reading txt file again, have $m has string, can this:

read -a arr <<< $m
