theorem Th17: :: SCMFSA9A:17
for p being Instruction-Sequence of SCM+FSA
for s being State of SCM+FSA
for a being read-write Int-Location
for I being really-closed MacroInstruction of SCM+FSA st I is_halting_on s,p & s . a = 0 holds
DataPart (Comput ((p +* (while=0 (a,I))),(Initialize s),((LifeSpan ((p +* I),(Initialize s))) + 2))) = DataPart (Comput ((p +* I),(Initialize s),(LifeSpan ((p +* I),(Initialize s)))))
