Design a simple full-screen editor on a video display terminal. The editor allows text to be inserted, deleted, and modified. Sections of text can be "cut" from one part of the file and "pasted" to another part of the file. The user can specify a text string, and the editor can find the next occurrence of that string. Through the editor, the user can specify margin settings, page length, and tab settings. Then, evaluate the quality of your design.
