The field attributes cannot store all of the information about the fields and characters in the presentation space. Extended character and color attributes for each field and character in the presentation space are also stored.
Each field has an extended attribute byte (EAB) that defines the extended attributes for that field. Extended attributes are returned using the getExtPS method (Javadoc and .NET) for any of the Screen object types.
Extended character attributes define characteristics that apply to the entire field. Extended character attributes control character attributes such as:
Extended color attributes define the foreground and background colors for each character in a field.
The following table lists all of the possible extended character attributes, and indicates whether or not each attribute applies to a particular Screen object type (3270, 5250, T27, UTS, or VT).
The ALC emulation is driven by a 6-bit protocol that does not include field attributes. |
