In the Method Source window, the next line of code to be executed is highlighted in blue (or the selected color of your choice). Lines of code are displayed as follows.
Only the first line is highlighted if an instruction is spread over more than one line.
Instructions within a loop are highlighted for each iteration of the loop but loop instructions are highlighted once only.
When you step through code, the highlighted instruction is kept visible by the lines of code scrolling as necessary.
If the selected line of the method has no compiled byte code, the breakpoint is set on the next source line that has byte code. If there is no source line following with byte code, the breakpoint is set at the beginning of the method.
Bubble help displays the current value of the variable or object over which the mouse is positioned and you are running the application in standard (fat) client mode.
You can turn the display of bubble help on or off, if required. For details, see "Setting the Animate Speed and Toggling the Bubble Help Display", later in this chapter.
