The following has the same output as John's way:
my @Bobs_way = glob "@ARGV" unless ! @ARGV;
print "Bob\'s way:\n";
for $arg (@Bobs_way) {print "- $arg\n";};

A little background on my question.
Basically I want people to be able to say something like
prog page*.html morebookmarks.html
For Unix users, I want to be lazy and have the shell glob that for me. For
Windows users, I want to be lazy and have the perl function glob that for
me.

Hi,
If I get the concept of globbing properly, I have been able to prevent it in Unix by
quoting my parameter list. I'm not sure how this works for spaces, but it helps a lot
with CGI stuff. When I do this, I use an test for STDIN, and if its not preloaded,
take @ARGV from the command-line as

But glob 'absent_file.txt' returns ('absent_file.txt') so I think this does
what's required. As perldoc says, glob EXPR returns the value of EXPR with
filename expansions such as the standard Unix shell /bin/csh would do.

The problem is that it will also glob th

properly. Surely the answer is:
my @input_files = map glob, @ARGV;
which will also leave @input_files empty if @ARGV is empty.

Is there a better way to say:
my @input_files = glob (join " ", @ARGV) unless $#ARGV = -1;
foreach my $doc ( @input_files ) { ... __code goes here___ }
I put the unless clause in there because otherwise...
if there are no file arguments, @input_files ends up having an element [0]
