Token Domains
A token domain is like an alpha domain but has specific values that are stored as corresponding numbers.
The token domain overlay, shown in Figure 2-3-13, allows you to add token specific attributes to those already defined for domains. The token domains specification overlay displays after you complete the entries on the domains screen if the domain Type you select is TOKEN.
Figure 2-3-13. Token Domain Overlay
The Token Domain Specifications overlay contains the following fields:
· Length designates the number of character positions, or length, of this domain.
· Lowercase OK? indicates whether or not a modifiable item
on an interactive screen can be entered in upper- and lowercase letters.
If “no” 
, the entry is stored and displayed exclusively
as uppercase, regardless of how a user enters the information. This entry
does not affect statements. A lowercase value established with a statement
displays as lowercase, even if this specification prohibits lowercase
entries. The default is “yes” 
.
· Descriptive provides a longer, more easily understood alternative to Field Name, one that is not required to be unique within an application. If blank at all default levels, Field Name is used.
· Column Hdgs designates up to two lines of column heading text. The APPX output process facility uses this text to generate standard column heading images for Start of Page and Start of Range class frames. For cosmetic reasons, the length of headings should not exceed the length of a field itself. Refer to Standard Column Heading Image for additional information.
For Token domain type, the following options are available as described in the corresponding sections:
