While

FilledSmallSquareWhile[test, body] evaluates test, then body, repetitively, until test first fails to give True.

FilledSmallSquareWhile[test] does the loop with a null body.

FilledSmallSquare If Break[ ] is generated in the evaluation of body, the While loop exits.

FilledSmallSquareContinue[ ] exits the evaluation of body, and continues the loop.

FilledSmallSquare Unless Return[ ] or Throw[ ] are generated, the final value returned by While is Null.

FilledSmallSquare Example: i=0; While[i < 0, tot += f[i]; i++]. Note that the roles of ; and , are reversed relative to the C programming language.

FilledSmallSquare See The Mathematica Book: Section 2.5.9.
