I really don't see any need for it. You can vary the WHILE condition to get the same results.
I = 1
REPEAT
   ? I
   I = I + 1
UNTIL I > 5


I = 1
DO WHILE I <= 5
   ? I
   I = I + 1
ENDDO
REPEAT UNTIL bloats the language with an unnecessary construct unless the execution time for evaluating the condition one extra iteration becomes important.
