The difference is that Perl reads the entire file into memory when you do a
"@file = ", but it only reads one line at a time if you do a
"while()". The difference definitely becomes clear if you try to do
that with a 180MB file on a machine with 128MB RAM.

I think your pattern match will only catch a literal AZ_OK, not the
constant. And I'm not sure, but AZ_OK might evaluate to 0. At least I
think I remember having trouble with that module because it returns 0 on
success, and I kept testing for TRUE/FALSE based on the return status.

Usually you do this by returning a 0 if the sub fails or any other value if
it is successful.
Simple Example:
if(lookforfolder()){
print "It's there!\n";
}else{
print "Folder not found\n";
}
sub lookforfolder{
if(-d "/home/me"){
return 1;
}else{
return 0;
}

This will work for the most part, but I would really recommend against it.
Check out the docs for Getopt::Std. It is much simpler than Getopt::Long,
and will really end up simplifying your scripts, although it might not seem
like it at first look.
Here's an example of a script that uses Getopt:
Try this:
my $string = 'I love c++';
my $compare = 'some compare string';
if ($compare =~ /\Q$string/) { #disables metacharacters until \E
print "$compare contains $string\n";
} else {
print "$compare does not contain $string\n";
