2.6.1 Calculation Errors

 

When NExS encounters a computational error, a descriptive message is displayed on the Message Line. In addition, the word Error followed by the message appears highlighted in the affected cells. If there are multiple errors flagged in the body of the spreadsheet, the message on the message line represents the first calculation error encountered. For example:

If you try to invert a 3 x 2 matrix, NExS highlights the cell where the formula was entered, and displays the message, ``Error - @INVERT, matrix must be square'' in the cell containing the invalid formula. In addition, the message, ``Cell xx:Error - @INVERT must be square'' appears on the Message Line.
