Proof step 30:
_length = fs ', st[r1 -- i '] = refval(r0), st[r1 -- _length] = byteval(by0), 0 ≤ i, i < byteval(by0) .intval, is_arraytype(st[r1 -- _type] .type), fits(r0, sks0, st), is_referencevalue(st[r1 -- (i ' ' + sks0)]), is_array(str, r1, st), 0 < byteval(by0) .intval, is_referencevalue(st[r0 -- sks0]) → junkref(str, r0, st) ∨ fits(r0, sks0, st[r1 -- _length, byteval(by)]) ⊦ r1 = jvmref, junkref(str, r1, st), ¬ byteval(by) .intval ≤ i ∧ fits(r0, sks0, st[r1 -- _length, byteval(by)])
