Regex Expressions

[John_L]

alright, cool thanks. I'm also having problems concatenating strings from standard input. My subroutine is called that contains a string in $_[0], which I want to concatenate with input from <stdin>. "." or "join()" doesn't seem to work. Can "\n" - new line characters cause problems when reading from standard input?

while( $line = <stdin> )
{
   $_[0] = $_[0] . $line  #doesn't work
   $_[0] .= $line           #doesn't work
}

what's the best way to get this to work?

yes, chomp() the input from stdin:

while ( chomp(my $line = <STDIN>)) {
$_[0] .= $line;
}
