Remarks
The setAttribute method is intended for use in a terminal emulation environment when modifications to the screen display data is needed at the server. For example, database reads can be used to modify displayed data when a list from the host is incomplete based on departmental requirements.
This method will change the display characteristics for the screen text which follows the location of the attribute.
This method works for both formatted (5250/3270 and unformatted (VT) displays.
Note - when used with the setDisplay method, you must specify the same starting location for both setAttribute and setDisplay.
