type is a string containing a sensible combination of the codes listed in the following sections. Note the following:
| • | Case is significant. |
| • | The codes are generally additive, and you can use as many as you want. For example, specifying both the codes for alphabetic and numeric types will result in an alphanumeric field. |
| • | The codes many be either single-character codes, or double or even triple character codes. All of the double-character codes begin with the lead-in character | (vertical bar.) All of the triple character codes begin with a pair of vertical bars. |
The codes are organized into the categories shown in the following topics. The final topic in this section, Type Codes Summary, shows all of the type codes in a single table.
