This also permitted step-by-step program execution in a true program animation manner with optional register and memory alterations simultaneously displayed. The advent of teletypewriter consoles in the 1960s allowed more interactive command line debugging capabilities but it was not until the early 1970s and the arrival of ubiquitous video monitors connected to mainframes that fully interactive, full screen debugging in multitasking environments became a reality. The core dump provided the state of the registers and memory at the exact moment of the deliberate 'crash'. Programmers have used machine code patches to implement single destructive breakpoints to cause a core dump since the early days of computers. The advent of multitasking limited the use of this option since the entire machine was halted. Įarly mainframe computers, such as the IBM/360, had console switches/dials that allowed breakpoints at specific instruction storage addresses and provided 'single cycle' operation, permitting the contents of registers and memory to be observed directly on console lights.

To make the program stop at a certain point, a cable was removed, called a breakpoint. In the initial design of ENIAC, program flow was set by plugging cables from one unit to another. In practice, a breakpoint consists of one or more conditions that determine when a program's execution should be interrupted.īreakpoints were invented for ENIAC, one of the earliest digital computers, by programmer Betty Holberton. During the interruption, the programmer inspects the test environment ( general purpose registers, memory, logs, files, etc.) to find out whether the program is functioning as expected. More generally, a breakpoint is a means of acquiring knowledge about a program during its execution.

It is also sometimes simply referred to as a pause. In software development, a breakpoint is an intentional stopping or pausing place in a program, put in place for debugging purposes. Panels with stack trace (upper left) and watched variables (upper right) can be seen. The debugging interface of Eclipse with a program suspended at a breakpoint.
