use a textfile and eval();

in the textfile:
var1 = 38273;
var2 = 382773;

read the textfile into var a and do eval(a) it will evaluate the text and assign the saved values

function save()
{
writetofile('var1 = ' + var1 + ';var2 = ' + var2 + ';');
}

function load()
{
  eval(readallfile()); // will assign corresponding var1, var2 values
}

this way you dont have to create/delete any registry values and the files will be removed when your script is removed by the user
