I just realised how to do this! - if the function is returning 4 numbers, 
then it may as well return an array, so we have:

function lorentz(A, B) array[]
{
    dim dx, dy, dz, dt : real;
    dim C[3];

    ' lorentz transformation code

    C[0] = dx;
    C[1] = dy;
    C[2] = dz;
    C[3] = dt;
    return C;
}
