This window is where the user can enter any relevant details that will describe in detail the function of the file and its relevance to the system in general. Any information entered here can the be printed out with the other file layout details to form part of the file layout documentation.
The user can enter up to 55 characters on each line. 4 lines at any one time appear on the screen. When these 4 are filled, the window clears down and another 4 lines can be entered. This process carries on indefinitely. Within windows such as this you can use function keys to move about - to review previous keyed lines, to 'page' through a window (review data a 'page'-at-a-time), to drop to the next free line in the data, to delete a line (and therefore move all the other lines up one) and so on.
