Common Usage Patterns
While overall usage of gotos has been declining, there are still situations in some languages where a goto provides the shortest and most straightforward way to express program's logic (while it's possible to express the same logic without gotos, the equivalent code will be longer and often more difficult to understand).
These situations include: multi-level breaks, resource allocation/deallocation, error handling in C language, computed goto in Perl language.

Famous quotes containing the words common, usage and/or patterns:
“Legends of prediction are common throughout the whole Household of Man. Gods speak, spirits speak, computers speak. Oracular ambiguity or statistical probability provides loopholes, and discrepancies are expunged by Faith.”
—Ursula K. Le Guin (b. 1929)
“Girls who put out are tramps. Girls who dont are ladies. This is, however, a rather archaic usage of the word. Should one of you boys happen upon a girl who doesnt put out, do not jump to the conclusion that you have found a lady. What you have probably found is a lesbian.”
—Fran Lebowitz (b. 1951)
“One can describe a landscape in many different words and sentences, but one would not normally cut up a picture of a landscape and rearrange it in different patterns in order to describe it in different ways. Because a photograph is not composed of discrete units strung out in a linear row of meaningful pieces, we do not understand it by looking at one element after another in a set sequence. The photograph is understood in one act of seeing; it is perceived in a gestalt.”
