If a Stored Process contains a required parameter named "var",
"switch", "export" or "class", a Javascript error message will be
displayed in your Web browser when you attempt to execute the
Stored Process.

The Javascript error message will be similar to the following:

   Line 13
   Char: 5
   Error: Expected identifier
   Code: 0
   URL: http://aa.bb.com:8080/SASStoredProcess/do?_program= etc.

When you attempt to execute the Stored Process, an "Error on page."
message will appear in the lower left corner of the Web browser.  When
you click on the "Error on page" message, a dialog window will be
displayed that says:

   "Problems with this Web page might prevent it from being displayed
    properly or functioning properly."

When you click on "Show Details", you will see the Javascript error
message noted above.

As a workaround, rename your parameter to something other than
"var", "switch" or "export".
