Proof step 49 from proof compat-addclass (previous step)

fis .keys = statfields(class0), mkfs(class, ty, fieldvar) ' ∈ statfields(class0), compatmode(str, st), compatrefs(str, st), okfieldinits(class0, fis), initdone(class0, addclass(class0, fis, st)), tdname∃(str, class0), (class∃(str, class0) ∨ interface∃(str, class0)) ∧ initdone(class0, st) → compatfields(str, jvmref, statfields(class0), st) ⊦ class = class0, compat(str, st[jvmref -- mkfs(class, ty, fieldvar) '], ty, addclass(class0, fis, st)) ∧ jvmref -- mkfs(class, ty, fieldvar) ' ∈ st

And obtained the following new goals

Proof step 48:
mkfs(class, ty, fieldvar) ' ∈ fis .keys, compatmode(str, st), compatrefs(str, st), okfieldinits(class0, fis), initdone(class0, addclass(class0, fis, st)), tdname∃(str, class0), (class∃(str, class0) ∨ interface∃(str, class0)) ∧ initdone(class0, st) → compatfields(str, jvmref, fis .keys, st) ⊦ class = class0, compat(str, st[jvmref -- mkfs(class, ty, fieldvar) '], ty, addclass(class0, fis, st)) ∧ jvmref -- mkfs(class, ty, fieldvar) ' ∈ st
