You lose, fella. The EMTP logic has detected an error condition, and is now going to terminate program execution. The following3 q* y% r' `: Q6 V
message summarizes the circumstances leading to this situation. Where an otherwise-unidentified data card is referred to, or where1 a2 D" T3 T3 t4 ~: n# p: b5 k
the "last" card is mentioned, it is the most recently read card of the input data that is meant. The 80-column image of this card$ p! F2 h) U( m7 m" B, u! \8 N3 Y
is generally the last one printed out prior to this termination message. But possibly this last-read card has not yet been L/ F/ e3 F$ Bdisplayed, so a copy follows:" t: J! [6 B% }; a
