  You spawn the command
"start <URL>" where <URL> is the Web page you want to display.
This is actually quite simple and elegant.
- The start command makes it run in the "background" so that IDL does not
wait for the
browser to exit
- It launches whatever application is associated with URLs, i.e. the default
browser.  Note that the
browser must be correctly installed for this to work.
- If there is already a browser running it displays the page on that running
browser.  If there
is not already a browser running it will start a new one.
for example:
spawn("start http://cars.uchicago.edu/software/mca.html";)
