When coding for the plug-in, also consider the following points:
Because your main application window is embedded inside the browser window, it cannot have the main window menu bar to which you may be accustomed. (This is a Microsoft child window restriction.) You can, however, program your application's menu functions to be accessed from a toolbar or a pop-up menu using the right mouse button.
When using QUIT-MODE, you may not accept or display anything after ACCEPT
terminates with the QUIT-MODE exception. If you do, the runtime terminates
immediately as if the program has executed a stop run.
When using "ACCEPT dest-item FROM COMMAND-LINE", dest-item will contain the full list of parameters from the HTML EMBED tag.
When making changes or enhancements to your code, we recommend saving your
object file under a new name (e.g., "myprog.acu", "myprog1.acu", and
"myprog2.acu".) This way, even if your users have previously downloaded your plug-in
application, they will automatically download the newer version the next time they
access your Web site.
When required, how will your application access local resources without
affecting end user security? Refer to section 5.9 for security issues that affect
coding.
