Above docs state, that a gernal parrot op looks like this op dest[dkey], src1[skey1], src2[skey2]
e.g. add P0[P1], P2, P3[P4] where P1 and P4 are keys and P0 and P3 are aggregates and P2 is a scalar. Several questions arise from these pdd's: 1) Are above pdd's valid, WRT this 3 key opcodes? 2) What PASM ops should above statement generate: a) add_p_k_p_p_k (i.e. all variations of /p(_k)?/ ) b) add_p_k_p_k_p_k if b) how to create a NULL key and how does it look like in PBC? Thanks, leo
