    Declaration

    Source position: portsh.inc line 47

    var
  portw: type

  tportw = object
  public
    property pp[w : Word]: Word read readport write writeport; default;
  end;

    Description

    Default instance of type TPortW. Do not free. This variable is initialized in the unit initialization code, and freed at finalization.

    Since there is a default property for a variable of this type, a sentence as 

    portw[221]:=12;

    Will result in the word 12 being written to port 221, if port is defined as a variable of type tport
