Try this.
$somestring =~ /^\d{14}$/;
# matches 0123456789123 but not 10123456789123
The ^ character matches the beginning of the string and the $ character
matches the end of the string.

$somestring =~ /\d{14}/;

Hi all,
I am trying to match a 14 digit number
When i use this regular expression i match a 14 digit number and any number
over 14 digits.
$somestring = ~ '/d{14}';
I have tried these combinations with no avail.
$somestring =~ '/d{14,14}';
$somestring =~ '[0-9]{14,14}';
$somestring =~ '[0-9]{14
Hi all,
Just wanted to thank everyone for their opinons on the subject. They were
very interesting. As I mentioned, at the college I am attending we are using

I think this is totally on topic, probably something that novices should be

Another simple one, I hope. I have data like this.

It didn't call any routines written in other languages? And what about
writing an OS?

The length (number of elements) of an array is returned when an array is
called under a scalar context.
@array = (1,2,3);
$size = @array; # $size gets 3, number of elements in array
print scalar @array; # prints the number 3
Hope this helps!
