The replace command incorporates the find command and allows you to not only to locate specific records but also to alter them.  It is very useful when it is necessary to make a change to a large quantity of identical records.  To demonstrate this, click on a field to highlight its records.  Click edit and click Find.  Click on the Replace tab.  Type in a phrase next to the Find what text box and the phrase you want to replace it with in the Replace with text box.  By clicking OK, all the words in the Find what text box will be changed to the ones in the Replace with text box.
