An IVIB Primer - Unicon

more interesting to tell the dialog what code to execute (namely, a call to the procedure p() mentioned earlier)
when the "go" button is clicked. Go over to the Events tab, click on Add, and associate a method on_go() with
ACTION_EVENT by clicking the Apply button.
Click OK, and then save your file. At this point if you go into file go.icn and look at the code, the Dialog has an
empty method
method on_go(ev)
end
into which we can insert a call to p() using the ui IDE, or emacs or another text editor:
method on_go(ev)
p()
end
Save go.icn with this call to p() added, and then compile go.icn and p.icn together (unicon go p), and run it
(./go). If successful, this application will run as described and write "Hello, world" to standard output when you
click the button.
Warning! Editing your file with Ivib and a text editor at the same time makes it easy for you to overwrite
