Specify the data block length.

Pointer to the IODBBTO structure including the tool offset value. The IODBBTO structure is as follows.

typedef struct  iodbbto {
    short datano_s;     /* start offset number */
    short type;         /* offset type         */
    short datano_e;     /* end offset number   */
    long  ofs[M];       /* offset value        */
} IODBBTO ;     /* Individual, Memory A all               */
                /*   M is number of the offset value.     */
                /* Memory B all                           */
                /*   M is number of the offset value x 2. */

datano_s

Specify the start tool offset number.
The available number is 1,...,9.
'This number + aux. function number which can be got by cnc_rdbtofsinfo function + 1' means the tool offset number for B axis which is used by NC command or display.

datano_e

Specify the end tool offset number.
The available number is 1,...,9.

type

Specify the tool offset type.
