Frame/Image Positioning
When you create frames and images for menu, input, and output processes, you are asked to define a size and display position for each.
· Sizes are stated in terms of the number of rows and columns a frame or image occupies. It is important to note that, while images consume physical space on the screen or printed page, frames do not. Frames simply designate regions for image placement.
· The position a frame or image occupies (where it displays on the screen or page) is determined by a number of factors, including the type of process, the way the process was invoked, and whether or not it includes a scrolling display.
You can surround frames and/or images in menu or input processes with a box. Boxes do not consume rows or columns within the space that is defined for a frame. They do, however, consume more physical space than overlines and underlines. The physical space on a screen that is consumed by a box is system-specific.
Various factors affect the actual positioning of a frame or image, as discussed in the following sections:

· The Effect of Scrolling Frames on Screen and Page Positioning
