## The PolyML.Debug structure

The PolyML.Debug structure contains functions to assist with debugging. For a tutorial see here.

    structure Debug :
      sig
        val breakAt : string * int -> unit
        val breakEx : exn -> unit
        val breakIn : string -> unit
        val clearAt : string * int -> unit
        val clearEx : exn -> unit
        val clearIn : string -> unit
        val continue : unit -> unit
        val continueWithEx : exn -> unit
        val down : unit -> unit
        val dump : unit -> unit
        val locals: unit -> unit
        val stack : unit -> unit
        val step : unit -> unit
        val stepOut : unit -> unit
        val stepOver : unit -> unit
        val trace : bool -> unit
        val up : unit -> unit
        val variables : unit -> unit
      end
