Setting background color in 4GL

Hello all: I have waiting for years from an Informix capability that makes posible set the background color for the screen interaction statements. I know that there isn't any syntax available for this in INFORMIX-4GL, but had anybody done something about this using termcap files, C functions, or something else?
