There is also a Mac version. An example of an external application which you might want to launch in this way from a Web page is the teleconferencing program CU-SeeMe . On the Mac Webrunner code was used, while on Windows GoCUSM performs the same function. Interactions between a Web browser and an external application need not be one-way. With many applications, you can also link back to Web pages for your browser to display.
Students can thus move easily back and forth between an external application and a Web browser.
One of the easier applications to do this with is HyperCard . Since HyperCard scripts can be written in AppleScript, you can easily write a short script to open a URL from within a HyperCard stack. This can be done with other Mac apps though through use of Flypaper . On the Windows side, VisualBasic allows for similar functionality. For the very ambitious, it is possible to write your own plug-in for further customization of your Netscape window.
