- While[test] does the loop with a null body.
- If Break is generated in the evaluation of body, the While loop exits.
- Continue exits the evaluation of body, and continues the loop.
- Unless an explicit Return is used, the value returned by While is Null.
- Note that in an example like i=0;While[i<0,tot+=f[i];i++] the roles of ; and , are reversed relative to C-like programming languages.
