i get: "Use of uninitialized value in concatenation (.) or string at 8.pl line 22"

... the file ... is not a table but arranged in 8 columns separated by space...

So, if you used the code as I posted it on the file that you describe, then yes, you would get that message about line 22 (the "print" statement) and no other output, because the split was based on /\t/ (as you had it in your original post), and with no tabs in the file, nothing would be assigned to $type. I gather you've gotten past that problem, and are moving on to the real job.

But the rest of your description of the job is hard to follow. If you are having trouble working it out, you'll need to show us some sample data that will make it clear what you are trying to do. If you are using two or more input files, and trying to relate information across the files to get specific outputs, show us a few relevant lines from each input, and what the corresponding output should look like. Then show us the code you've tried so far.

(Now that you've gotten past the issue of "splitting a table into individual columns", you might want this new information and question, about joining data from different inputs, to be the start of a new thread.)
