loop programming
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).
