Proof step 4 from proof is_array-putbar-01 (conclusion)

⊦ ¬ is_array(str, r, st) ∧ okbytearray(r1, st) → ¬ is_array(str, r, putByteArray(bytes, r1, i, st))

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 1:
⊦ is_array(str, r, st) ↔ type∃(str, st[r -- _type] .type) ∧ st[r -- _type] .type .jtelemtype ≠ void_type ∧ st[r -- _type] .type .jtelemtype ≠ abstract_type ∧ is_array(r, st)
Proof step 3:
okbytearray(r1, st), type∃(str, st[r -- _type] .type), is_array(r, putByteArray(bytes, r1, i, st)) ⊦ st[r -- _type] .type .jtelemtype = abstract_type, st[r -- _type] .type .jtelemtype = void_type, is_array(r, st)

Rule argument
