Adds an entire record of text to the grid at once. You must set DATA-COLUMNS beforehand to denote where each column's data starts. The record is usually added at the end of the grid, but you can change this by using INSERTION-INDEX. Note that the new record is added to the grid — it does not overwrite any existing data. Also note that RECORD-TO-ADD will not add an empty record. See CELL-DATA for a way to add individual cells to a grid. See INSERT-ROWS for a way to insert empty records.
