SCALEFACT

The address of the control block structure that contains the current row and column coordinate scaling factors. The scaling factors must be greater than or equal to 1 and less than or equal to (32K - 1).

typedef struct _SCALEFACT {
  ULONG     rowScale;  /*  Row scaling factor. */
  ULONG     colScale;  /*  Column coordinate scaling factor. */
} SCALEFACT;

typedef   SCALEFACT   * PSCALEFACT ;
