Some entries in this section refer to color and font values (for example, BGCOLOR and FONT). These values are color and font numbers established for your system. Some entries in this section also refer to character units, an ABL unit of measure for specifying portable widget sizes and positions in graphical environments. For more information on color and font values, or character units and their relationship to pixels, see OpenEdge Programming Interfaces.

Note: When you assign a decimal value to an attribute representing a measurement in character units, ABL automatically rounds the assigned value to the nearest decimal value that corresponds to whole pixel units.
