Hi I'm using the following code to extract some words from a file: my  @words = grep(s/[^a-zA-Z0-9]/ /g, @lines); the problem is that the words i want must contain a mix of both letters and numbers. 
jHj8nniO - good
I87jjj8y - good
jUjngnkk - bad
ikbHH - bad

[download]
the good words are the words that are a mix of letters and numbers. thanks for any help.
