Micheal,
Unsure what you are trying to do? You say you are picking from a
file which you are inputting via the command line. Then what? I see you
picking the the file then print the file. Is that what you want to do? The
while (<>) would read data in from one file after another until all files
are gone.
Need some other insight on what you are trying.
Wags ;)
