Hello again, Monks. I have a question for the collective genius of this monastery. I have googled for it, but I think I'm not asking google the right question. Here goes:

In my code, I have a piece that evaluates to a numeric value, either 4 or 6. In my test code snippet below, I am simply assigning the value statically for testing purposes. I want to use the value of this scalar in the name of an array further down in my code, so I can avoid "if else" blocks. However, this isn't working. I have read sites where the general consensus is that dynamic variable names are a bad idea, but based on the code that went along with those posts, I am not sure they apply to my situation. On to my code snippet:

#!C:/Perl64/bin/perl.exe

use strict;
use warnings;
use Control::CLI;

my $cli;
my $output;
my $temp;
my $junk;
my $port;
my $result;

my @STATION_LIST_6 = qw/A B C D E F/;
my @STATION_LIST_4 = qw/A B C D/;

...

my $STATION_CNT = 4;

my $FREEMEM;
print "Configuring blah blah blah...\n";
print "\tChecking free memory on appropriate blades to ensure there is
+ enough for application execution...\n";
    
foreach my $stid (@STATION_LIST_$STATION_CNT) {  <-- This line doesn't
+ work...
    $junk = $cli->print("echo STATION_\$stid; su -c \"ssh STATION_\$st
+id free -g\"");
    $output = $cli->cmd("password");
    $FREEMEM = $output =~ m/^.*?\w+:\s+\d+\s+\d+\s+(\d+)\s.*$/s

    if ( $FREEMEM >= 4 ) {
        print "\t\tSTATION_$stid reports sufficient free memory...\n";
    } else {
        print "\t\tSTATION_$stid reports insufficient free memory ($FR
+EEMEM)... Please investigate and start application again... Exiting p
+rogram.\n";
        exit;
    }
}

If anyone has any thoughts they could share, I would appreciate it. I REALLY want to avoid "if else" here, and dynamically figure out the value of the array to use. Thanks in advance, as always!
