The Free On-line Dictionary of Computing (30 December 2018):

repeat loop
do loop
repeat

    (Or "do loop") 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 BASIC loop "Hello" is printed once despite the fact
   that the condition is false;

    i = 2
    repeat
      print "Hello"
      i = i+1
    until i>0

   See also while loop and for loop.
