Your solution was incomplete (for example, you didn't insert the commas) so I deleted it. Please don't post incomplete solutions. We have two DFSORT developers (myself and Kolusu) answering posts here, so we really don't need your "help".
There are several people who contribute good solutions to this list besides myself and Kolusu. I have no problem with people contributing good solutions. But correcting bad solutions takes too much time away from our day jobs of developing DFSORT and ICETOOL. We participate in several help boards and gets many private e-mails asking for solutions every day. We're happy to help customers use DFSORT and ICETOOL effectively and efficiently, but we don't have time to correct bad or incomplete solutions and such solutions just serve to confuse people.
If you consider that "harsh", I'm sorry.
Maybe we should rename this the "Frank and Kolusu Forum".
No, it's correctly named the "DFSORT/ICETOOL Forum" and it's "staffed" by DFSORT/ICETOOL developers. I would think that having experts respond to the Forum would be considered helpful by most people. Would you want to call a helpline for a product and get "help" from somebody who didn't know the product well?
I said "your" help referring to THAT particular poster. From what I can tell, he just recently started using DFSORT/ICETOOL and is using this Forum to "practice". I advised him previously to feel free to practice all he wants, but not to post incomplete or untested solutions as they don't really help anyone. It's admirable that he wants to learn to use DFSORT/ICETOOL better, but at this point I believe he should be watching and learning until he becomes proficient at which point he can post all he wants.
