Default How to implement LOG function with PLANT

Hi,

Could anyone tell me how to input a formula like U1(z)=UTAU/K*LOG(Z/Z0). I tried to input this formula with the PLANT menu, but I got some error message telling me that the LOG is not a stored variable when compiling the GROUND. Is it not a built-in mathematical operator in PLANT? If LOG cannot be recognised by PLANT, what should I do? Please help!

Hu
