The keywords allowed in cntrl-string are listed in the following groups. If more than one keyword from within a group appears in cntrl-string, only the rightmost one in the data item is used:
The FCOLOR and BCOLOR keywords are used to set foreground and background colors respectively. These keywords must be followed by an equals sign and the name of a color taken from the following list: BLACK, BLUE, GREEN, CYAN, RED, MAGENTA, BROWN, and WHITE. The named color becomes the default foreground or background color for the window. Note that this is different from the COLOR phrase, which sets the color only for the current ACCEPT or DISPLAY statement. The FCOLOR and BCOLOR keywords set the default colors for every subsequent ACCEPT and DISPLAY until explicitly changed.
