theorem Th23: :: SFMASTR3:25

for s being State of SCM+FSA
for a being read-write Int-Location
for bb, cc being Int-Location
for k being Nat
for p being Instruction-Sequence of SCM+FSA
for Ig being really-closed good MacroInstruction of SCM+FSA st s . (intloc 0) = 1 & k = ((s . cc) - (s . bb)) + 1 & ( ProperForUpBody a,bb,cc,Ig,s,p or Ig is parahalting ) holds
DataPart (IExec ((for-up (a,bb,cc,Ig)),p,s)) = DataPart ((StepForUp (a,bb,cc,Ig,p,s)) . k)
