I suspect there are no entities defined for 
&requestBPROC; and &proc;

In both XML and HTML, parameter strings are processed in
a context where entities are expanded.  Using an undefined
entity produces an undefined result, although most HTML
browsers will treat the initial & as a literal in that case.

See http://www.w3.org/TR/html40/appendix/notes.html#h-B.2.2 for
the correct way to code hrefs and for ways to write CGI (ASP,
PHP, etc.) scripts to minimise the problem.
