extra print commands

Im not sure how to work the question. But im learning CGI and i saw the command

print p("<b>Thank you for your order $name!</b>") ;

what does the methond p() do? And are there any other like this one? IE i saw qq() on one question and it said it is for double qoutes.

thanks

i think it is an error unless the experts think otherwise

infact it would be helpful if you post the full code where you saw the command

use CGI qw(:standard);

print header,

my $who = param("name");
my $flavor = param("flavor");
my $scoops = param("scoops");
my $taxrate = 1.0743;
my $cost = sprintf("%.2f", $taxrate * (1.00 + $scoops * 0.25));
print p("Ok, $who, have $scoops scoops of $flavor for \$$cost.");
} else { # first time through, so present clean form
print hr(); # draw a horizontal rule before the form
print start_form();
print p("What's your name? ", textfield("name"));
print p("What flavor: ", popup_menu("flavor", ['mint','cherry','mocha']));
print p("How many scoops? ", popup_menu("scoops", [ 1..3 ]));
print p(submit("order"), reset("clear"));
print end_form(), hr();
}
print end_html;

If you're using the CGI module, the 'p' function just puts the text in a <p> tag pair.

An interesting thing about most of the html shortcut functions supplied by CGI.pm — p( ), b( ), h1( ), h2( ), etc — is that they are are all generated from the same template using the autoloader.

Fantasy has answered both parts of your question. I suggest you accept his answer. Of course, we're ready to explain more if need be.
