How to define a variable that depends on a variable calculated from ODE?

Hi,
I need to define a global variable Pc to update my boundary condition for each time step. The variable Pc depends on m, which is calculated using a Global ODE at each time step. So it's like:
initial boundary condition with initial Pc > solve heat equation > calculate m using Global ODE > calculate Pc >update boundary condition
My problem is, I'm not able to give Pc an initial value for the first time step when defining it in Global Variables. How can I make this work? Either is there a way to define the boundary condition with a different expression for the first step, or is there a way to define the variable Pc with an initial value?
Thanks a lot!
