That's a common problem.
To oversimplify, a scalar context is a situation where an expression is
expected to return just one thing, like
my $var = func();
This calls func() in a scalar context.
Suppose func was
sub func {
my @ray = 0..9;
}
$var would be 10, because the return from func() would be the value of
the array assignment; an array in a scalar context returns the number
of elements. (Again, list, please correct me if I fumble this.)
On the other hand, using the same function,
my @lst = func();
would assign the numbers zero to nine to @lst, because it's a list
context -- a situation in which more than one thing is expected.
Better? =o)
