Row SelectionTo select rows from the table, provide either a list of row ranges or a conditional expression.
By rangeA row range is in the form of first_row-last_row. You can give a list of row ranges separated by commas, e.g
1-20, 25, 30-100
Use the calculator and column buttons to create a boolean formula (or type one in directly), indicating which rows should be selected. All the rows that satisfy the condition (expression evaluates to TRUE, or not equal to zero) will be selected.
When the "Select" button (or <Return> key) is pressed, fv will highlight the selected rows in the table.
See the calculator help page for information on how to specify the conditional expression.
Go to About fv.
