The test is evaluated first; however, you can achieve the effect of its being evalated last. n = 0; While[n < 3, Print[n]; n++] 0 1 2 n = 0; While[n < 3, Print[n++]] 0 1 2 n = 0; While[n < 3, n++; Print[n]] 1 2 3 n = 0; While[n++ < 3, Print[n]] 1 2 3 Bob Hanlon On Sat, Dec 10, 2011 at 7:30 AM, Joao <joaopereira9 at gmail.com> wrote: > Hi, everybody > > Could someone help me regarding the While Loop. > > While[test,body] > > In the help "While" it is stated that the test may be evaluated at the end of the loop, instead of at the beginning.

This is a feature that would be useful for what I'm doing, however I haven't been able to get it working and I don't know, taking into consideration the above, if I am doing something wrong or if it is really not possible to do. > > Thanks in advance > > Joao >
