Setting and Using Breakpoints

If you suspect that there is a bug within a statement which is the 1,000th program statement executed, it's not terribly convenient to single-step to it. Instead, you would like to run the program until you get ``near'' the suspect statement or subroutine and then single-step the program. You would like to ``break'' (suspend) program execution at a particular point within the program --- a breakpoint. From that point, you can use Run|Step over or Run|Trace into.

Breakpoints are set by moving the cursor to an executable statement where you would like a break to occur and choosing Debug|Toggle breakpoint. This line is then highlighted. Repeat this process until you have all the breakpoints which you want. Choosing Run|Run causes the program to execute until the first breakpoint is encountered. Choosing Run|Run again will run the program until the next breakpoint (possibly the same one as before) occurs. Choosing Debug|Toggle breakpoint on a line which has a breakpoint already set removes the breakpoint.

Debug|Breakpoints contains several advanced breakpoint options. Among these are editing breakpoints, setting qualifier conditions for breakpoints, and setting a skip count for a breakpoint. Refer to the on-line documentation for details.
