repeat loop
do loop
do while
repeat

    (Or "do loop", "repeat until") A loop
   construct found in many procedural languages which
   repeatedly executes some instructions while a condition is
   true.

   Repeat loops are found in Perl, Pascal, BASIC and C.
   The initial keyword may be "repeat" or "do" and the
   condition may be introduced with a "while" or "until" keyword.

   In constrast to a while loop, the "loop body" is executed
   once before the condition is tested.  This is useful when the
   condition depends on the action of the loop body.  In the
   following, "Hello" is printed once despite the fact that the
   condition is false;

    i = 2;
    do 
      print "Hello"
      i = i + 1
     while (i < 1);

   See also while loop, for loop, loop-and-a-half.
