theorem :: EXTPRO_1:34

for N being non empty with_zero set
for S being non empty with_non-empty_values IC-Ins-separated halting AMI-Struct over N
for F being Instruction-Sequence of S
for s being State of S
for k being Nat st F halts_on Comput (F,s,k) & 0 < LifeSpan (F,(Comput (F,s,k))) holds
LifeSpan (F,s) = k + (LifeSpan (F,(Comput (F,s,k))))
