substr
Quick question, when using substr, how can you refer to more than two letters, say the 1st, 2nd and 3rd bar simply joining more than one substr together?

Hmm. I'm not really sure what you're asking. . .
Are you looking to concatenate two substrings together? Code:
my $string='foobar'; my $substring1=substr($string,0,3); my $substring2=substr($string,2,3); my $totalstring=$substring1.$substring2; #which could also be my $totalstring=substr($string,0,3).substr($string,2,3); #In both cases, $totalstring is "foobar"

That's what I was doing in my substr() above. Read the docs about substr at the address above. Fortunately, they are pretty clear in this case.
