monochrome bitmap display device as white text on a black background.

property you specified. Specify the argument in form coordinate system

SET_CANVAS_PROPERTY restrictions
• You cannot enter a non-existent named visual attribute.
• If Form Builder cannot find a named visual attribute by the name you supply, it looks for the display
attribute in your Oracle*Terminal resource file.

** canvas color at runtime to the name of a visual attribute
