A method for visually displaying an indicator for preceding and succeeding source code lines being executed within a graphical debugging environment. The method includes displaying within a GUI source code lines for a segment of currently examined source code, displaying a visual indicator that is associated with a presently examined source code line, and determining a previously examined source code line, wherein the location of the previously examined line of source code is determined by the use of information that is associated with the previously examined line of source code. The method further includes displaying a visual indicator that is associated with the previously examined line of source code, determining a next source code line that is to be examined, and displaying a visual indicator that is associated with the next source code line that is to be examined.
