Need Help??

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

Hi all,

I want to print the following -

Seán Connery
[download]

with the following code

my $f = "\x{0301}";
$html = qq(

<html>Sea$fn Connery<html>

);
print html;
[download]

But perl sees $fn not $f, what should I do?
Cheers,
Barry.

`<html>Sea${f}n Connery<html>` [download] should do.	[reply] [d/l]

You need to tell perl where the variable name stops and where the rest of the text begins, using curlies. Without such a distinction in the example below, "$var12" could mean either `$var12` or the value given by `join( '', $var1, '2' )`. `use strict; use warnings; my $var1 = 'one'; my $var12 = 'twelve'; print "$var12\n"; # prints 'twelve' print "${var1}2\n"; # prints 'one2'` [download] This is discussed in perldata, "Scalar value constructors".
