Use this command when debugging a program that contains an error-handling procedure. Break On Errors (toggled on when a bullet appears next to the command) causes your program to stop at the first statement in the most recently executed error-handling subroutine. This suspends program execution so you can locate the source of the error. Turning on Break On Errors also enables the History On toggle, so the 20 statements executed just before the breakpoint are also recorded. Use the Shift+F8 key once to back up to the statement that caused the error. Backing up further will show you the statements that lead to the error.
