Introduction to B and GSL (Cont.) • B-Method based on Generalized Substitution Language (GSL) by Abrial. – [x := E]R ≡ The predicate obtained after replacing all free occurrence of x in R by E. – [P | G]R ≡ P&[G]R – [P =⇒ G] ≡ P ⇒ [G]R – [skip]R ≡ R – G‖H ≡ apply the substitutions G and H concurrently. – [G; H ]R ≡ [G]([H ]R) – [G[]H ]R ≡ [G]R&[H ]R
