Baz has asked for the wisdom of the Perl Monks concerning the following question:

I wish to print the value of param(0) inside quotes, so if param(0) stores 10 i want to print '10', the following code prints 'param(0)' which is fair enough but not what i want.. 
print("\'param(0)\'");

what should I be doing?

    Param is a function, and function calls are not interpolated in double quotes like variables are (not until perl 6, anyways). You want to do this:

    print "'",param(0),"'";

    There are many ways to do this: 
    print '"' . param(0) . '"';
print "'" . param(0) . "'";

my $form_value = param(0);
print "'$form_value'";
print qq|'$form_value'|;

    Hope this helps ...

    Make the return of param(0) a reference, then wrap it in ${}:

    YuckFoo

    print "${\param(0)}\n";

      If you're going to do it "inlined" like that I'd recommend putting it inside a derefed array ref. 
      @{[scalar .... ]}

      As in:

      #!/usr/bin/perl -wT
use strict;

print "Yours: ${\localtime()}\n";
print "Mine:  @{[scalar localtime() ]}\n";

__END__
