Hello everybody! Relatively fresh to Perl hence need support. I am parsing in two data files which have a list like this: 102l,0,GLU,,11,S,PSIBLAST,206l of about 5000 entries, I am interested in seeing how many values of the first column, e.g 1021, match with values of the other file. I guess I would need to parse everything into a hash and match the keys with the keys from another hash but inexperience is having trouble extracting the information. Do I store everything into an array first and then split and use a regex for a match? Thanks in advance. Ada.
