Please know that I am not normally one for just giving up code. Its not condusive to your learning. But, this is one of those times where I am inclined to do so.

You would do something like the following which is a substitution, replacing all digits with nothing.

Untested, but I think it should work.

Expand|Select|Wrap|Line Numbers

1. $string =~ s/\d//g;
2.

Thank you again!

probably a bit more efficient:

c = compliment of search pattern
d = delete

tr/// is very good for these simpler type of task requiring a regexp. s/// is good for the more complex stuff.

That's helpful! Thank you!
