EFILive provides the same set of operators as 'C'. (Except for equality in C is ==, in EFIlive it is just = and non-equality in C is !=, in EFILive it is <>). And there is no ?: operator, use the built in function iff() instead.
So create a calcualted PID that returns 0 or 1:
iff({GM.STATE05} & 128,1,0)
Then use that calculated PID in the filter.
