Set vars (by reference) in function

Hello everyone,
I am curious to find a possible way of doing something like this in ksh:
call a function and have that function set the value of the variable that the function knows by the name of $1....
example:

#! /bin/ksh
set_var(){
case $1 in
var1) this is where I would like to set var1 to a particular value;;
var2) this is where I would like to set var2 to a particular value;;
var3) this is where I would like to set var3 to a particular value;;
esac
}

set_var "var1"
set_var "var2"
set_var "var3"
# Now I would like to see what these values where set
echo $var1
echo $var2
echo $var3

Is this possible?
Hope you can help give me ideas.
Thanks.
