let S be non empty 1-sorted ; for i being Element of SCM-Instr S st ( InsCode i = 1 or InsCode i = 2 or InsCode i = 3 or InsCode i = 4 ) holds

let i be Element of SCM-Instr S; ( ( InsCode i = 1 or InsCode i = 2 or InsCode i = 3 or InsCode i = 4 ) implies JumpPart i = {} )
assume

then

then

hence
