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). | |
