I am trying to concatenate
some text, a scaler, and more text
to create a reference. I am not quite getting there. the code:

#!/usr/bin/env perl
use strict;
use warnings;

my $MaxScanId = 45;
my $a = "Scan";
my $b;
my $c;
my $d;

print "a $a, maxScanId $MaxScanId \n\n";

$b = "Max".$a."Id";

$c = "\$".$b;

print "c: $c \n\n";

$d = \$c;
print "d: ${$d} \n";

[download]
results:

a Scan, maxScanId 45

c: $MaxScanId

d: $MaxScanId

[download]

The results of the final print are not quite what I was looking for, (I expected the contents of $MaxScanId, 45)
What am I missing. I am sure there is a simpler way to do this (in a single step, perhaps),
But I have only been using perl about 30 days so I need lots of help
Always did, but that's another issue

$a is the name of a database table, ScanId is the primary key, and $MaxScanId holds
the value of the next available id (saves an SQL query each time the routine is called).
