FORTRAN program to extracting column
Dear folks

I have a large data set which contains 400K columns. I decide to select 50K determined columns from the whole 400K columns. Is there any suggested fortran program which could do this process for me? I need to also mention that I store all of the columns id in one file which may help to select those columns out of the whole 400K columns.

Regards
Saj
