Ok first off im going on the assumption that the files will always be the same name, second off I am assuming that you know what data you want every time. Also apparently your data file only has one line? If not then you are only getting the last line from the file each time. I have moved any ||'s and &&'s to newlines so that the code doesn't wrap so much 
#!/usr/bin/perl
$base1   = "C:/neaq/ArcData/bluefin/data_analysis/1994sptr/data";
$base2   = "C:/neaq/ArcData/bluefin/data_dens/1994sptr";
$outfile = "C:/some/dir/to/reports";

opendir(BASE1, "$base1") || die "Cant open $base1\nReason: $!\n";

foreach $file ( grep(/\.txt$/, readdir(BASE1)) ) {
   warn "Skip: No matching $file in $base2\n" 
      && next unless (-f "$base2/$file");

   open(IN, "$base1/$file") 
      || die "Cant access $file\nReason: $!\n";

    while ( <IN> ) {
      @data1 = ( split(/\s+/) )[1,2,3,4,5,6,7];
    }
   close(IN);

   open(IN, "$base2/$file") 
      || die "Cant access $base2/$file\nReason: $!\n";

   while ( <IN> ) {
      $data2 = ( split(/\s+/) )[3];
   }
   close(IN);

   open(OUT, ">>$outfile") 
      || die "Cant append to $outfile\nReason: $!\n";
   print OUT "@data1 $data2\n";
   close(OUT);

} # END foreach $file readdir(BASE1)
#
# or alternately to save up our data and only print once
# push(@out, join(' ', "$file: ", @data1, $data2));
# then loop through out once and print it out here instead
