print "a= $a\n";
print "b= $b\n";

You may have to modify the regex and the structures for non-Perl
languages since @ is a special char in Perl and may not be in others.
The regex here matches everything from the beginning of the string
up to the first @, not including the @, and puts it in $1 or \1
(first backreference).

But if this was all I wanted, I might use a substr instead of a
regex, since regexes are a bit more complex than what you said
you wanted. (Don't use a .50 to shoot a chipmunk, etcetera....)
