ABSTRACT

Some programs must be able to  interact,  that  is,  be
able  to  interleave input and output operations.  Con-
sider, for example, how a text editor must be  able  to
reply  to  each  command before requiring the next com-
mand.  Interactive behaviour  cannot  be  described  in
most  functional languages.  Previous techniques to en-
able interaction, such as ``lazy  evaluation''  destroy
some  of  the  elegance  and simplicity of a functional
language.  We propose a new  technique  that  preserves
the advantages of functional languages.
