Hi,

Further to my idea of presorting the hash keys described in Re^2: Perl Program - Out of memory? (rather that sorting them again and again), I would suggest that you try the following modified program. 

#USAGE EXAMPLE - Max Points Replaced If Higher Value Found
require 'funcs_top10.pl';

my $delay = 3;
my $maxSalary = 100000;
my $programStartTime = localtime();
my $maxPoint;

my $qbHash = getStats("QB"); #Sorts Player Statistics Into Hashes Acco
+rding To Position
my $rbHash = getStats("RB"); 
my $wrHash = getStats("WR"); 
my $teHash = getStats("TE");
my $dstHash = getStats("DST"); 
my $flHash = getFlexStats();

my @qb_keys  = sort keys %$qbHash; 
my @rb_keys  = sort keys %$rbHash;
my @wr_keys  = sort keys %$wrHash;
my @te_keys  = sort keys %$teHash;
my @dst_keys = sort keys %$dstHash;
my @fl_keys  = sort keys %$flHash; 

foreach my $key (@qb_keys) {
    my $QB1i = $qbHash->{$key}->{PlayerID};
    my $QB1s = $qbHash->{$key}->{Salary};
    my $QB1p = $qbHash->{$key}->{FPPG};
    my $QB1pos = $qbHash->{$key}->{Position};
    #print "QB1 count = $qb1count \n";
    #$qb1count++;

    foreach my $key (@qb_keys) {
        my $QB2i = $qbHash->{$key}->{PlayerID};
        my $QB2s = $qbHash->{$key}->{Salary};
        my $QB2p = $qbHash->{$key}->{FPPG};
        my $QB2pos = $qbHash->{$key}->{Position};
        #print "--QB2 count = $qb1count \n";
        #$qb2count++;
        next if $QB1i == $QB2i;

        foreach my $key (@rb_keys) {
            my $RB1i = $rbHash->{$key}->{PlayerID};
            my $RB1s = $rbHash->{$key}->{Salary};

                my $RB2i = $rbHash->{$key}->{PlayerID};

                my $RB2p = $rbHash->{$key}->{FPPG};
                my $RB2pos = $rbHash->{$key}->{Position};
                #print "------RB2 count = $rb2count \n";
                #$rb2count++;
                next if $RB1i == $RB2i;

                foreach my $key (@wr_keys) {

I made the following changes: presorting the hash keys into arrays and using the arrays of keys to walk though the data, added my statements to declare your variables so that you can enable warnings and strictures (I might have missed some, I can't really test or compile).

Three additional points: (1) I do not see the point of using a delay in your most inner loop, I think you can remove it. (2) The fact that you did not give lexical scope to your $key loop variable is probably a major bug in your program, because I think that the $key variable at one level of nesting gets overwritten by the last value taken by $key within the next nested loop (not entirely sure though, I have not tried in ages to use such loop variable without lexically scoping it, maybe Perl can manage this correctly, but I would be surprised). OTOH, it may have no impact because starting the inner loop is the last thing you do each time, but this is poor and dangerous design. Anyway, this should no be the case with my version above, where each $key variable is lexically scoped within its loop. (But, again, I can't test anything.) (3) Finally, the $salary variable used at the end of the program seems to be coming from nowhere. Using warning and strictures would detect this, just as the fact that you are using $maxPoint and $maxPoints.
