Viewing code coverage results in an editor
You can open the source file or listing and view its code coverage results in the editor. Code coverage uses the editor assigned in the client's Preferences.
By default, a green bar next to the line number indicates that the line was covered, a red bar
that it was not covered. You can hold your mouse over the indicator to see the coverage specifics,
as shown here.
For PL/I source files with 
%INCLUDE statements, in addition to the
number of lines being covered, the information about the included files is also displayed.
