A sequence of instructions that the processor repeats, either until some condition is met, or indefinitely. In an structured language (e.g. C, Pascal, BASIC, or Fortran), a lOOP is usually achieved with for lOOP, {while lOOP} or {repeat lOOP} constructs. In other languages these constructs may be synthesised with a jump (assembly language) or a GOTO (early Fortran or BASIC). (1999-05-06)
