(Command "Opendcl")



(Defun C:Dock ()



   ; Call The Method To Load The Hello.Odcl File.



   (Dcl_Project_Load "Gddock" T)



   ; Call The Method To Show The Hello World Dialog Box Example



   (Dcl_Form_Show Gddock_Form1)



   (Princ)

(Defun C:Gddock_Form1_Textbutton1_Onclicked (/)



  (Command "_Layer" "In" "*" "O" "") 

)





(Defun C:Gddock_Form1_Textbutton2_Onclicked ( /)



  (Command "_Layer" "Ac" "*" "") 

)





(Defun C:Gddock_Form1_Textbutton3_Onclicked ( /)

In OpenDCL Studio, change the 'EventInvoke' property for those two buttons to '1 - Allow Command'.
