I read of a perl function called param, which is part of the CGI.pm
perl library. The first simple program I wrote trying to use it didn't
work though. At first I thought the ISP hosting my site didn't provide
this library, but I was able to use other commands from it such as:
print start_html;
Sometimes it's difficult to debug what's in your CGI
environment. That's what Inside is for:

I tried perldoc -f param and got nothing.
Since the function comes from the module, it's documented in the module:
perldoc CGI
#!/usr/local/bin/perl
use CGI ':standard';
print "Content-type: text/html\n\n";
$value = param('myvalue');
print ("The value = $value");
Maybe that code doesn't work for you because you're not printing HTML,
like your header claims you are. You could change the type in the
header to 'text/plain', or you could change the output section. Have
you tried running it from the command line? Doing that is described in
the CGI module's documentation.
Also, of course, the usual admonitions to 'use strict', 'use
warnings', and so on.
Hope this helps!
