Q:  How do I initialte a DDE link to the program manager to create a new group?

A:  Here it is from c:\delphi\demos\dde\ddedemo.dpr:

var
  Name: string;
  Macro: string;
  Cmd: array[0..255] of Char;
begin
  if GroupName.Text = '' then {an edit field on the form}
    MessageDlg('Group name can not be blank.', mtError, [mbOK], 0)
  else
  begin
    Name := GroupName.Text;
    Macro := Format('[CreateGroup(%s)]', [Name]) + #13#10;
    StrPCopy (Cmd, Macro);
    DDEClient.OpenLink;
    if not DDEClient.ExecuteMacro(Cmd, False) then
      MessageDlg('Unable to create group.', mtInformation, [mbOK], 0);
    DDEClient.CloseLink;
    GroupName.SelectAll;
  end;
end;
