(while testexpr [expr...]) 

The while function continues until testexpr is nil.

The following code calls user function some-func ten times, with test set to 1 through 10. It then returns 11, which is the value of the last expression evaluated:

(setq test 1)

(while (<= test 10)

  (some-func test)

  (setq test (1+ test))

)
