No, that will not work.  First, that will output the following for a line
that is "hello there!":

chop(hello there!)

Second, you would not use chop, but chomp.  Chop takes off the last
character of the string; chomp removes the last character online if it is a
line break character.

Third, chop/chomp returns 1 if successful, 0 if not; it does not return the
string.  So if you did C<print OUT chomp($_);>, you would get 1 or 0, not
the line.

while(defined(<IN>)) {
  chomp;
  print OUT "$_ ";
}
