DELTAT is the time-step size, and the division involves integer truncation followed by the addition of unity. % k8 w8 K+ P$ b4 b' z3 }( i6 bIn order to effectively trade memory space among the different EMTP tables (EMTP List Sizes), the user must know how many arrays ( j( |& E, g5 o2 ](columns) there are in each table.
