Try this my man...
my @nums = split(/[a-zA-Z]+/,$stat);
Hope this helps.

Subject: Pattern Matching - Remove Alpha
I am unable to use "split" with pattern matching to remove alpha
characters
from a string and will appreciate a pointer on what I'm doing wrong.
(Have
looked in "Learning Perl" and "Programming Perl" but can't spot my
error.)
The detail:
"$stat" is a string that has alpha and numeric data in it.
I want to remove all of the alpha and put the numeric data into an
array.
The first attempt:
my @nums = split(/a-zA-Z/,$stat); # removes all data from the string
The second attempt:
my @nums = split(/a-z/,$stat); # removes all data from the string
From reading, my understanding of "split": Discards all data that
matches
the pattern and returns a set of list values for the unmatched data.
("my
understanding" may be the problem)
This pattern works - removes all blanks (white space) but leaves alpha
and
numbers which of course isn't what I want
my @nums = split(/ +/,$stat); # removes all blanks
