This all depends on how you want to pull apart your data. If you want the
first four letters and only the first four letters, regardless of what the
text is, then you can use the substr() function:
my $part2 = substr $part1, 0, 4;
If you specifically want the first *word*, then you need to do something
more generalized, using a pattern matching algorithm. For instance, this
will give you all of the words in the above variable as a list that you
can stuff into an array, using the split function, which lets you split a
string based on a particular pattern
my @parts = split /\s/, $part1;
Are you working out of a decent introductory tutorial or book on Perl?
