theorem Th48: :: SCM_HALT:66

for p being Instruction-Sequence of SCM+FSA
for s being State of SCM+FSA
for I being really-closed good InitHalting MacroInstruction of SCM+FSA
for a being read-write Int-Location st not I destroys a holds
( (IExec ((I ";" (SubFrom (a,(intloc 0)))),p,s)) . a = (s . a) - 1 & ( s . a > 0 implies DataPart (IExec ((Times (a,I)),p,s)) = DataPart (IExec ((Times (a,I)),p,(IExec ((I ";" (SubFrom (a,(intloc 0)))),p,s)))) ) )
