BlooP is a non-Turing-complete programming language whose main control flow structure is a bounded loop (i.e. recursion is not permitted). All programs in the language must terminate, and this language can only express primitive recursive functions.

FlooP is identical to BlooP except that it supports unbounded loops; it is a Turing-complete language and can express all computable functions.

BlooP and FlooP can be regarded as models of computation, and have sometimes been used in teaching computability.
