while
     
         the loop construct found in nearly all
        imperative programming languages which executes one or more
        instructions the "loop body" repeatedly so long as some
        condition evaluates to true.  in contrast to a repeat loop,
        the loop body will not be executed at all if the condition is
        false on entry to the while.
     
        for example, in c, a while loop is written
     
        	while  ;
     
        where  is any expression and  is any
        statement, including a compound statement within braces
         "..".
