Picking up on the "Any help appreciated" comment:
- Always use strictures (use strict; use warnings;)
- Use lexical file handles
- You only need to call binmode once
- Use Perl for loops to advantage - avoid indexing where it's not needed
so your code could look like:
use strict;
use warnings;
my $fn = "delme.bin";
my $bName = 'eps_cm_0_pblk1';
my %gBuf = (eps_cm_0_pblk1 => ['0x00000019', '0x0000001b']);
open my $binOut, '>', $fn or die "Couldn't open '$fn' for writing: $!n
+";
binmode $binOut;
foreach my $element (@{$gBuf{$bName}}) {
print $binOut pack ('C', hex $element);
}
close $binOut;
True laziness is hard work

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).
