<h1>Breakpoints</h1>

<p>A breakpoint suspends the execution of a program at the location where the breakpoint is set.
|
|
|
15 |
To set a line breakpoint, right-click in the marker bar area on the left side of an editor beside
|
|
|
16 |
the line where you want the program to be suspended, then choose <b>Toggle Breakpoint</b>. You can
|
|
|
17 |
also double-click on the marker bar next to the source code line. A new breakpoint marker appears
|
|
|
18 |
on the marker bar, directly to the left of the line where you added the breakpoint. Also, the new
|
|
|
19 |
breakpoint appears in the Breakpoints view list.
|
|
|
20 |
</p>
|
|
|
21 |
<p>Once set, a breakpoint can be enabled and disabled by right-clicking on its icon or by
|
|
|
22 |
right-clicking on its description in the <b>Breakpoints</b> view.
|
