It's right there in the CGI documentation (perldoc CGI):
FETCHING THE NAMES OF ALL THE PARAMETERS PASSED TO YOUR SCRIPT:
@names = $query->param
If the script was invoked with a parameter list (e.g.
"name1=value1&name2=value2&name3=value3"), the param() method w
+ill
return the parameter names as a list. If the script was invoke
+d as an
<ISINDEX> script and contains a string without ampersands (e.g.
"value1+value2+value3") , there will be a single parameter name
+d "key-
words" containing the "+"-delimited keywords.
