Am I missing something?

print "[EMAIL PROTECTED] has ", scalar(@F), " entries\n";
}

Subject: [Boston.pm] make split return empty entries?
Hi, question from a most-times lurker. I'm reading in a
bunch of lines of the form
A,B,C,D,E,F
with the split statement:
my @F = split ',', $line;
However, sometimes the trailing fields are blank:
A,B,C,,,
In this case, @F will only contain 3 entries, since split
will not count the trailing null entries. This screws up my
code later on. It'd be much easier to assume @F always has
6 entries.
By reading perldoc -f split, I wasn't able to find a way to
make split count those entries. Is there a way to make
split count trailing null entries?
Many thanks for any help, I can work my code around this,
but it's a bit of a pain in the @$$...
