Sentence length, word variety, readability, and overall structure can be analyzed by these programs.

So far we have discussed only the ways the computer helps improve the content of a piece of writing. But as most effective communicators realize, the appearance of a document can also send a message.
Word processors make setting margins, adding footnotes or headers, and paginating almost effortless.
Graphic-based word processors not only allow the writer to underline, boldface, or italicize words, but to actually change the style and size of the font. These features are great fun for reluctant writers, and useful features for students doing persuasive or creative writing. Finally the edited document can be quickly printed. Typed or printed documents get more serious attention paid to them than hand written papers. They are easier for teachers and other students to read.
