Hi Don,

I presume that in linux OS, awk has not limitations of the file size? And i've no clue about bytes calculations Smilie

Your assumptions to my problems are pretty accurate except that the values in each columns are not fixed, in other words, it might have other letters or combinations of 2 letters.

I would need to use this kind of program in my other analysis works. (i'm working on quantitative genetics, dealing with DNA data).
