I have a Perl script that is being deployed at several different sites. To allow each site to customize the appearance of the HTML generated, I have an INI file with a number of NAME=VALUE pairs. What I'm wondering is if there is a way to assign a value to a variable name that is stored in a variable. For example, if I have the following in my INI file:
$NAME=John Smith
I'd like to be able to read $NAME into $var1 and John Smith into $var2, and then assign what's in $var2 to the variable name stored in $var1.
I can currently work around this. Here is my script thus far:
sub read_ini()
{
my @file = read_file("recorder.ini");
my $line = 0;
my $pos = 0;
my $var = "";
my $val;
for(@file)
{
if(substr(@file[$line],0,1) ne "#")
{
$pos = index(@file[$line],"=");
if($pos > 0)
{
$var = substr(@file[$line],0,$pos);
$val = substr(@file[$line],$pos + 1, length(@file[$line]) - $pos);
if($var eq "NAME")
{ $NAME = $val; }
elsif($var eq "OFFICE")
{ $OFFICE = $val; }
# And so on for other instances
}
}
$line++;
}
}
Can I use a hash to accomplish what I described above? I'm sorry for sounding ignorant, but I'm still new to Perl.
Thanks!

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).
