The problem ! m& q- G3 K9 o3 E/ i/ R' C5 Ois simply too big for the program as currently dimensioned. Yet, do not forget dynamic dimensioning as described in the Oct., 1993, 7 o, Z( S; u9 Q" p0 @!

Sometimes the reason for EMTP table overflow is unclear, and Program Maintenance might wish to inspect the contents of the error % s- |1 t% m0 ]interface vectors LSTAT and FLSTAT. These now follow.

In order to effectively trade memory space among the different EMTP tables (EMTP List Sizes), the user must know how many arrays4 [2 z5 T7 g. N/ H
