How can I get the 5th and 6th letters from an 8 letter code and assign them to a scalar variable?

For example, if the code is ABCDEFGH I'd like the scaler to have the value of EF.
thanks,

you don't need a reg. substr function will take care of it.

my $code="ABCDEFGH";
my $fifthAndSixth = substr($code, 4, 2);

substr(string, index of char to start, how many char in total including the starting char);

index of char in a string starts with 0, thus the '4' is the above snippet for the fifth char in the string. 'man perlfunc' for more details.

If you insist to use reg, you can use something like,

my $code="ABCDEFGH";
my $fifthAndSixth;
if ($code =~ /^\w{4}(\w{2})\w{2}$/) {
     $fifthAndSixth = $1
}
else {
     print "invalid code: <$code>\n";
}
