Conditions for Auto-calculation of Cell Formulas on Workbook Load

If the WKBK_AUTO_CALCULATE_ONLOAD application preference is defined and selected, when a workbook is opened, then all workbook cells that have a formula are re-calculated automatically. If the WKBK_AUTO_CALCULATE_ONLOAD application preference is not defined, or is defined and is cleared, when a workbook is opened, then all workbook cells that have a formula are not re-calculated automatically.
