One small correction. The CauseID and the EventID are not always the same. Especially for most of the entries in the $SPECROOT/SS/CsVendor/EventDisp file:
0x00010d2e E 50 A 5, 0x00010412
0x00010d09 E 50 A {v 1},0x00010700
0x00010034 E 50 A 6, 0x00010007,N
0x00010daa E 50 A 2, 0x010701,N
0x00010d19 E 50 A 5, 0x00010003,N
0x00010d35 E 75 A 3, 0x00010009,N
0x00010d36 E 75 A 5, 0x00010004,N
0x00010d40 E 50 A 6, 0x00010404,N
0x00010d41 E 50 A 3, 0x00010405,N
