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

About print p,
this is the cgi.m shortcut key for adding the <p> pair. You can also print others tag like this for example: print br(..., print hr(...), print h2("this is font2")

About qq:
By default the print function, and most other Perl functions, use the " sign to deliminate. Using the qq command, we can pick a replacement for the " sign so we can use the " sign inside the print without needing to escape it.

Instead of writing:

  print "\"Hello\", Joe said.";
You could also write:

  print qq!"Hello", Joe said.!;

Thanks & Cheers

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,

start_html("Ice Cream Stand"), h1("Ice Cream Stand");
if (param()) { # the form has already been filled out
    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();

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.
