11 * The fields of BASEOP are:
12 * op_next Pointer to next ppcode to execute after this one.
13 * (Top level pre-grafted op points to first op,
14 * but this is replaced when op is grafted in, when
15 * this op will point to the real next op, and the new
16 * parent takes over role of remembering starting op.)
17 * op_ppaddr Pointer to current ppcode's function.
18 * op_type The type of the operation.
19 * op_flags Flags common to all operations. See OPf_* below.
20 * op_private Flags peculiar to a particular operation (BUT,
21 * by default, set to the number of children until
22 * the operation is privatized by a check routine,
23 * which may or may not check number of children).
