4gl Input array question?

4GL 4.12, SE 5.01, SCO Unix 3.2v4.2 I have a table with 8 columns. I want to let the user update, delete, or insert to a screen array with only 6 of the columns displaying. How can I do this when the number of variables in the screen array must match the program array? For simplicity sake, I want to let 4gl handle the array and when the user is done modifying the array, I want to delete all of the rows in the table and insert all of the changed rows from the screen/program array TIA Matt Brickley
