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)
