Proof step 18 from proof compatfields-mode (previous step)

r -- mkfs(class0, ty, fieldvar) ' ∈ st, mkfs(class0, ty, fieldvar) ' ∈ instfields(class), r ∈ st, compat(str, st[r -- mkfs(class0, ty, fieldvar) '], ty, st) ⊦ r = jvmref, compat(str, st[r -- mkfs(class0, ty, fieldvar) '], ty, st[_mode, val])

Proof step 14:
⊦ compat(str, val, ty, st) ↔ okval(val, ty) ∧ ( is_referencevalue(val) ∧ val .refval ≠ jvmref → val .refval -- _type ∈ st ∧ is_typevalue(st[val .refval -- _type]) ∧ is_reftype(st[val .refval -- _type] .type) ∧ (has_classtype(st[val .refval -- _type] .type) → tdname+∃(str, st[val .refval -- _type] .type .jtelemtype .class)) ∧ (is_classtype(st[val .refval -- _type] .type) → class+∃(str, st[val .refval -- _type] .type .class)) ∧ asgcomp(str, val, ty, st))
Proof step 17:
