 To '''debug''' a [[program]] is to find and remove any errors ('bugs') in it. There are a number of ways to do this.
-The earliest was to use the computer's [[front panel]], and [[single-step]] through the program, looking at the sequence of [[instruction]]s [[execute]]d, the contents of [[register]]s, etc. When [[batch]] [[operating system]]s came in, the usual approach was to take a '''core dump''' (a printout of the contents of [[main memory]]); this was laborious, and not an efficient use of the [[programmer]]'s time.
