Proof step 44 from proof fits-put (previous step)

¬ r -- i0 ' ≠ r1 -- i ', st[r -- i0 '] = refval(r0), r1 ∈ st, okarray(r1, byte_type, st), is_array(str, r, st), 0 ≤ i0, 0 < st[r -- _length] .intval, i0 < st[r -- _length] .intval, is_arraytype(st[r -- _type] .type) ⊦ (st[r1 -- i ', byteval(by)][r -- i0 ']) = refval(r0), r1 = jvmref, r = jvmref, junkref(str, r, st)

And obtained the following new goals

Proof step 43:
st[r1 -- i '] = refval(r0), i < st[r1 -- _length] .intval, okarray(r1, byte_type, st), r1 ∈ st, 0 ≤ i, 0 < st[r1 -- _length] .intval ⊦ r1 = jvmref, junkref(str, r1, st)
