I don't know exactly what you're trying to do, but I should warn you
that your question is not as simple as you might think. (Certainly not

The expression should have been this:
@vars = $string =~ /([0-9a-z]+)/gi;
This will collect all alphanumeric strings into @vars.
> it should take the word until the first space.
The problem is defining what the "word" is.
1) It only works for simple upper- and lowercase English letters. If you
have any special letters, they will break up the strings. For example:
'cafe' (with an accent on the e) will become 'caf'
'resume' (with accents on both e's) will become 'r', 'sum'
"doesn't" will become 'doesn', 't'
'Ph.D.' will become 'Ph', 'D'
'1,000-12,500' will become '1', '000', '12', '500'
'either/or' will become 'either', 'or'
There are no simple expressions that will cover all of these cases. (Any
internationalization gurus out there disagree?)
2) Non-English text might not work at all. Many European languages have
special letters not covered by a-z/A-Z.
