    I wanted to build a variable dc supply with maximum voltage of
    12v.When the resistance across the rehiostat is zero the regulator
    output is 12v. But the output increases above 12v when Ivary the
    resistance across the rehiostat above zero.Is that what should happen?
    if yes why is that? if no what should i do? If you can suggest me
    another way of desigening variable dc power supply also....

    It'll depend on the circuit which we don't have available to make any useful
    comment. Is it available online ?
