%X This paper describes an experiment in providing explicitly
parallel constructs in the style of occam within a
functional programming environment. The work is based upon
the monadic style proposed and described by Moggi, Wadler,
Peyton Jones and others. The approach is pragmatic and
conservative in that parallelism is treated as an imperative
feature implemented by monadic functions. Overloading is
used to provide a class of channel protocols. As in occam,
data transmitted over a channel is fully evaluated and must
be of ground type. An algorithm for checking channel usage
in the presence of dynamic process and channel creation is
described. The work can be described as an extension of
functional notations allowing for explicit imperative\-style
parallelism. Alternatively, one could view it as extending
the vocabulary of the occam language to allow for recursion,
higher\-order constructions and dynamic process and channel
