This is a one-line VB5 application to overcome a limitation in the 32-bit Novell Application Launcher; i.e., you can't launch a data file (or URL) but only an application.
If you don't know which application is to be used with the data (for example you may have users with different versions of Netscape, or indeed IE). RNAPP32 uses the standard explorer associations to launch your app. So make the executable RNAPP32 and put the data file (or URL) as command line parameters.
It's been tested on Windows 95 and Windows NT 4.0, though I can't see any reason why it won't work on other Windows 32-bit platforms.
The only error checking is to see if there is a command line parameter.
