The running of a program can be controlled with breakpoints. Breakpoints stop a running program at a specific statement.
To set breakpoints, perform the following steps:
- Place the cursor on the line of code where you would like to set a breakpoint.
- Press F6 (Add/Clear breakpoint) to set the breakpoint.
- Press F12 (Resume) to run the program.
Note: Just before the line of code runs, where the breakpoint is set,
the program source is displayed indicating that the breakpoint was hit.

When you hit a breakpoint, if you want to set breakpoints that are only hit within the current thread, use the TBREAK command.
