echo variable problem

hi

I have say five variable.

I would ask the user which one they want me to print and then print accordingly.


TEST_1='10.2.3.4'
TEST_2='11.2.3.5'
TEST_3='12.2.3.5'
TEST_4='13.2.3.5'
TEST_5='14.2.3.5'

print_var()
{
echo "Accessing var num $1"
echo TEST$1
#??? But How do I print the value of say TEST_1 here base on user input

}
echo -n "Please enter the var num: "
read num
print_var $num
# 2
