Thanks Matt,
But this code is for a dcl not for opendcl,or I'm wrong.
I have a make a textbutton
(defun c:start_Start_Tekstlayer25_OnClicked (/)
(dcl_MessageBox "To Do: code must be added to event handler\r\nc:start_Start_Tekstlayer25_OnClicked" "To do")
)
But where put I the code to start the lisp.
I'm do not find in the samples of opendcl.
