can be seen as a subset or subdiscipline of imperative programming, one of the major programming paradigms.

Go To Statement Considered Harmful
was instrumental in the trend towards structured programming
Description of the inverse relationship between a programmer's ability and the density of goto statements in his program is repeated.
