4.3 Calculation Settings Block
Definition: Calculation Settings Block
The calculation settings for a sheet are stored in several records in the Worksheet Stream (BIFF2-BIFF4) or
Sheet Substream (BIFF5-BIFF8), called the Calculation Settings Block. Note that the settings are global for the
entire workbook document in BIFF5-BIFF8, but most of the records occurs equally in every Sheet Substream.
Structure of the Calculation Settings Block:
○ UNCALCED ➜5.105 (BIFF3-BIFF8 only)
○ CALCCOUNT ➜5.13
○ CALCMODE ➜5.14
○ PRECISION ➜5.79 (moved to Workbook Globals Substream in BIFF5-BIFF8)
○ REFMODE ➜5.85
○ DELTA ➜5.34
○ ITERATION ➜5.61
○ DATEMODE ➜5.28 (moved to Workbook Globals Substream in BIFF5-BIFF8)

4.4 Page Settings Block
Definition: Page Settings Block
The records in the Page Settings Block describe options and settings for printing. The record block is contained
in the Worksheet Stream (BIFF2-BIFF4) or in every Sheet Substream of the workbook (BIFF5-BIFF8).
Structure of the Page Settings Block:
○ HORIZONTALPAGEBREAKS ➜5.57 (seperated in BIFF2-BIFF4, see below)
○ VERTICALPAGEBREAKS ➜5.108 (seperated in BIFF2-BIFF4, see below)
○ HEADER ➜5.55
○ FOOTER ➜5.48
○ HCENTER ➜5.54 (BIFF4-BIFF8 only, seperated in BIFF3)
○ VCENTER ➜5.107 (BIFF4-BIFF8 only, seperated in BIFF3)
○ LEFTMARGIN ➜5.66
○ RIGHTMARGIN ➜5.86
○ TOPMARGIN ➜5.104
○ BOTTOMMARGIN ➜5.11
○ PLS ➜5.78
○ PAGESETUP ➜5.73 (BIFF4-BIFF8 only)
○ BITMAP ➜5.6 (BIFF8 only)
In BIFF2-BIFF4, Excel does not write the HORIZONTALPAGEBREAKS and VERTICALPAGEBREAKS records
together with the other records of this block (BIFF2: ➜4.2.1; BIFF3: ➜4.2.2; BIFF4: ➜4.2.3). In BIFF3, additionally the
HCENTER and VCENTER records occur at another place (➜4.2.2). Anyway, it is valid to write all records together
when a document is exported.
