Hi there!
Thanx!
That's all I needed to know! :-)

Now is the time I will start to quote the manpage at you:
$ perldoc -tf glob
glob EXPR
glob In list context, returns a (possibly empty) list of filename
expansions on the value of EXPR such as the standard Unix shell
/bin/csh would do. In scalar context, glob iterates through
such
filename expansions, returning undef when the list is
exhausted.
This is the internal function implementing the "<*.c>"
operator,
but you can use it directly. If EXPR is omitted, $_ is used.
The
"<*.c>" operator is discussed in more detail in "I/O Operators"
in perlop.
Beginning with v5.6.0, this operator is implemented using the
standard "File::Glob" extension. See File::Glob for details.
See the sentence "in scalar context"? What part of that is unclear?
Please learn to read the manual. If you have *questions* about the
manual, or can't *find* it in the manual, that's fair game for this
list. But I don't think you will make many friends asking us to quote
the manual for you.
