FLDATTR=ON/OFF     (default is ON)

fldattr is used to disable "field" attributes, to avoid display problems caused by programs assuming "field" emulation, when the actual display device is operating as a "mode" terminal. See FIELDEMU under OPTIONS for a discussion of the difference between "field" and "mode" emulations.

When FLDATTR is off, "field" attribute commands, such as reverse video and underline, are ignored. Doing without your reverse video and underline highlights is better than having them spill over the screen incorrectly, as would otherwise happen if your application was not written to support both field and mode emulations.  

FLDATTR=OFF is equivalent to OPTIONS=NOFLDATTR.
