I need help to working OpenEdge Architect.
How could write external procedures and call them into forms.
I'll assume you already have a project and have created a form and are able to run.
Create a file named "test.p" and put something in it. Perhaps something like:
message "hi world" view-as alert-box.
Create your form with a button on it.
Add an event handler for the click event of the button. Just double-click on the botton in the VD and it will add the event handler.
Add a run statement in the method and run the program.
Run your form (use the run button on the main toolbar) and press the button.
