Abstract
A text processor is capable of creating table data based on numerical values and mathematical expressions entered through a keyboard, and displaying the data on a display screen. The text processor avoids unnecessary re-calculation of table data by a) allowing a user of the text processor to selectively inhibit automatic recalculation of mathematical expressions, b) recalculating only mathematical expressions whose operands and/or mathematical operators have been changed, and c) providing indication to the user as to which mathematical expressions have been changed and require recalculation.
