The variable $formatThis is not known as a "package-variable", because it just a variable for the subroutine. You can do it this way:
#!/usr/bin/perl
use strict;
use warnings;
my $OBJ = {test => 3};
my $p = 'test';
A();
sub A {
my $formatThis = sub {
my ($x) = @_;
my $y = sprintf ( "%.2f", $x);
return $y;
};
if ( exists $OBJ->{$p} ) {
my $q = $OBJ->{$p};
$q = $formatThis->($q);
print "$p=$q ";
}
$formatThis;
}

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
