We cover indexing in more depth later in the chapter. A text field can store up to 2GB of information, limited by RAM and hard drive space, of course, and indexes up to approximately 100 characters, depending on what language you're using. The only requirement is that it be character based in other words, you can't place a picture in a text field. Users can enter any range of information in them, including carriage returns, and there's no expectation of what form or sort of information a text field will hold. Text fields are the most free-form of the field types. Although FileMaker can convert a text field to a number where necessary, it can apply numeric formatting only to a number field. This allows you to use FileMaker Pro editing and formatting. Use the most specific field type you can.
