let S be non empty stored-program IC-Ins-separated definite standard-ins standard regular AMI-Struct of N; for F being NAT -defined FinPartState of holds IncAddr F,0 = F
let F be NAT -defined FinPartState of ; IncAddr F,0 = F
for m being natural number st il. S,m in dom F holds
F . (il. S,m) = IncAddr (pi F,(il. S,m)),0
proof
let m be
natural number ;
( il. S,m in dom F implies F . (il. S,m) = IncAddr (pi F,(il. S,m)),0 )
assume
il. S,
m in dom F
;
F . (il. S,m) = IncAddr (pi F,(il. S,m)),0
then
pi F,
(il. S,m) = F . (il. S,m)
by AMI_1:def 47;
hence
F . (il. S,m) = IncAddr (pi F,(il. S,m)),
