SETTING THE VALUE(S) OF A NAMED PARAMETER:

    $query->param('foo','an','array','of','values');

This sets the value for the named parameter 'foo' to an array of values. This is one way to change the value of a field AFTER the script has been invoked once before. (Another way is with the -override parameter accepted by all methods that generate form elements.)

param also recognizes a named parameter style of calling described in more detail later:

    $query->param(-name=>'foo',-values=>['an','array','of','values']);

			      -or-

    $query->param(-name=>'foo',-value=>'the value');
