In  BIFF8  this record stores used magnification factors for page break

    magnification,  when the view is changed. The real magnification of the
    currently  active  view  is  stored  in the SCL record. The type of the
    active view is stored in the option flags field (see below).

*** This class appends the optional SCL record ***

Record SCL, BIFF4-BIFF8:

This record stores the magnification of the active view of the current worksheet.
    In BIFF8 this can be either the normal view or the page break preview.
    This is determined in the WINDOW2 record. The SCL record is part of the
    Sheet View Settings Block.

    2       2       Denumerator [denominator] of the view magnification fraction (den)
    The magnification is stored as reduced fraction. The magnification results from num/den.
