Character to number and back again

[BobZwick]

How do I convert a character string 101 to a numeric value, increment it to 102 then convert it back to a charater string ?

Thanks a bunch!

Perl doesn't strictly type strings and numbers, so you really don't have to worry about it. This will work just fine:

$x = "101";
$x++;
print "x = $x";

It would print out 102.

Perl's attitude is: If you use it as a string, it's a string. If you use it as a number, it's a number. Most of the time it doesn't make any difference.
