The spreadsheet calculator sc is based on rectangular tables much like a financial spreadsheet. When invoked it presents you with a table organized as rows and columns of cells. If invoked without a file argument, the table is initially empty. Otherwise file is read in (see the Get command below). Each cell may have associated with it a numeric value, a label string, and/or an expression (formula) which evaluates to a numeric value or label string, often based on other cell values.
