You lose, fella. The EMTP logic has detected an error condition, and is now going to terminate program execution. The following # q' K* M7 O9 ?, rmessage summarizes the circumstances leading to this situation. Where an otherwise-unidentified data card is referred to, or where* a9 `) L& T0 g# v
the "last" card is mentioned, it is the most recently read card of the input data that is meant.

In order to effectively trade memory space among the different EMTP tables (EMTP List Sizes), the user must know how many arrays S, g# v" E# s/ _+ R/ e
