consider M being non empty Subset of NAT such that
M = { (locnum l) where l is Instruction-Location of S : l in dom F }
and
A1:
FirstLoc F = il. S,(min M)
by Def2;
A2:
FirstLoc F in dom F
by Th21;
A3:
il. S,0 <= il. S,(min M)
by AMISTD_1:28;
then
il. S,0 in dom F
by A1, A2, AMISTD_1:def 20;
then
FirstLoc F <= il. S,0
by Th23;
hence
FirstLoc F = il. S,0
