Hi there, Thanks for your reply, I had tried something using the /g global earlier but I discounted it for changing every variable every time, here is what I had: 
#!/usr/bin/perl
#subs4.plx
use warnings;
use strict;

#try using /g global to remember where I'm up to in a match
my $pattern;
$_ = "Three, Four, One, Two";

print ("\t\tCounting Program\n\n", $_, "\n\n");
my $correct;

print "Is this sequence correct?(yes/no)\n";
    $correct = <STDIN>;
    chomp ($correct);
    

while ($correct ne "yes"){
    print "Is the first number correct?\n";
    my $first = <STDIN>;
    chomp ($first);
    
    if ($first ne "yes"){
        print"What should it be?\n";
        $first = <STDIN>;
        chomp ($first);
        /([A-Z][a-z]+)/g;
        s/$1/$first/g;
        }
    
    print "Is the second number correct?\n";
    my $second = <STDIN>;
    chomp ($second);
    
    if ($second ne "yes"){
        print"What should it be?\n";
        $second = <STDIN>;
        chomp ($second);
        /([A-Z][a-z]+)/g;
        s/$2/$second/g;
        }
    
    print "Is the third number correct?\n";
    my $third = <STDIN>;
    chomp ($third);
    
    if ($third ne "yes"){
        print"What should it be?\n";
        $third = <STDIN>;
        chomp ($third);
        /([A-Z][a-z]+)/g;
        s/$3/$third/g;
        }
    
    print "Is the fourth number correct?\n";
    my $fourth = <STDIN>;
    chomp ($fourth);
    
    if ($fourth ne "yes"){
        print"What should it be?\n";
        $fourth = <STDIN>;
        chomp ($fourth);
        /([A-Z][a-z]+)/g;
        s/$4/$fourth/g;
        }
    
    #Final print
    print ($_, "\n\n");
        
    print "Is this sequence correct now?(yes/no)\n";
    $correct = <STDIN>;
    chomp ($correct);            
    }

After running through each of the <STDIN>'s the final print is "Four, Four, Four, Four" - in retrospect this is possibly the closest I got to my actual solution! This is what prompted me to ask the question where-in I was looking for a way to ignore the first match of a RegEx the second time it's run. Again, thank you for your help, I feel I am close to a solution. -- Just had a thoguht pre-posting, it is possible (but perhaps not elegant) to run the RegEx /A-Za-z+/, save the result to a variable and substitute the match with whitespace.. then call the variable later.. but thinking about it this is just a cheat/hack and not really using the substitute fnction of a RegEx.
