Editing Breakpoint (section)

=== Interactive breakpoints ===
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 monitor]]s connected to [[mainframe computer|mainframe]]s that fully interactive, full screen debugging in multitasking environments became a reality. This also permitted step-by-step program execution in a true [[program animation]] manner with optional register and memory alterations simultaneously displayed. Initially this type of animation was at the level of [[disassembler|disassembled]] or [[decompiled]] machine code, but later advanced to [[high-level programming language|HLL]] source level animation.
