The output of the above example is a button with the message:

When this button is clicked, the URL http://exforsys.com displays in a new window. This is because the first argument mentioned is http://exforsys.com and the second argument mentioned is _blank, denoting that the URL loads into a new window. The URL displayed in the new window has its window width as 300 and its height as 500. The value of width and height are mentioned as 300 pixels and 500 pixels respectively. The windows displayed have the scroll bars, tool bar, status bar displayed because the value of scrollbars, status and toolbar is set to yes, making these visible in the window. The window displayed is not resizable and is fixed in size because the resizable feature is set to no. The value of the menubar is set to no, displaying no menu bars in the final output window.
