Here's the current code. When I run it under the debugger, all is well until I get to the my $hdr line. When I step through this and (in the debugger) type p $hdr, it returns nothing; the same is true when I type p @colnames even though p $data returns the whole data array. I'm new at this, so I don't really understand how the FILEHANDLEs work. Even though this syntax seems correct, it doesn't seem to really open that array. I'm lost. 
sub subgen {
        my($data) = shift;
    chomp($data);
    my($cur_segno) = 0;
    my(@sst) = ();
    
        open(FILE, $data); # or die "Cannot open: @data\n";
    
    my $hdr = <FILE>; #read in the first line 
    chomp $hdr;
    my @colnames = split /, ?/, $hdr; #split the header into an array
