It's very easy to display a LONG field. Just define the the field length attribute to the maximum text length (up to 64 K) and overwrite the default key-edit trigger with edit-field(x, y, width, height). Then the user will be able to scroll through the long column. You may want to disable the update-allowed attribute for the LONG column. If the display attribute isn't a problem this method of creating a pop-up for help text will give you a minimum of programming work since the edit-field packed procedure will automatically wrap the text for you according to its display parameters.
