I have a problem with printout in a small script I have written. It's something I have never seen before and I cannot see why it is happening.

The relevant code is as follows. (Everything before it is just input gathering) 

for $station (@stations){
    print "\n    $station";
    print OUTFILE "\n$station";
    undef %found;
    splice @found;
    for $stage (@stages){
        chdir "/opt/stc/db/$station/$stage/prod/doc";
        @files = <MO*>;
        for $file (@files){
            open HTMFILE, "< $file";
            for $line (<HTMFILE>){
                if ($line =~ /${monobj}/ && $line =~ /HREF/ && $line !
+~ /TOP/){
                    $found = $stage,$file";
                    $found{$found} = (split /-/, $line)[0];
                }
            }
            close HTMFILE;
        }
    }
    @found = sort (keys %found);
    for $found (@found){
        ($stage) = (split /,/, $found)[0];
        print "\t- $stage - $found{$found}\n";
        print OUTFILE ",$stage,$found{$found}\n";
    }
    print "\n" if ($found[0] eq "");
    print OUTFILE "\n" if ($found[0] eq "");
}

Any print statement within the 'for $station ...' loop is withheld until the start of the 'for $found ...' sub loop. So the line print "\n    $station"; right at the top does not print until the start of this last sub loop.

It's not a major issue. The printout looks exactly how I want it but it is bugging me. Since the @files can contain between 2000 and 3500 entries, it would be nice to have the value of $station printed out where I put it as this would give a better progress indication.

All suggestions gratefully received and tried.
