Using extended data stream terminals
You can use fixed extended data stream attributes by reassembling the physical map set or for dynamic attribute medication, by reassembling both the physical, and symbolic description map sets.
Applications and maps designed for the 3270 Information Display System run unchanged on devices supporting extensions to the 3270 data stream such as color, extended highlighting, programmed symbols, and validation. To use fixed extended attributes such as color, you only need to reassemble the physical map set. If dynamic attribute modification by the application program is needed, you must reassemble both the physical and symbolic description map sets, and you must reassemble or recompile the application program.
