I use anonymouse variables all the time. Basically in dynamic database applications.
It makes very complicated things a bit easier :
@files = `ls /home/user`;
foreach $file(@files) {
open file...
@$file = <FILEHANDLE>;
close file...
}
Open fileto contrain contents of all files ...
foreach $file(@files) {
print FILEHANDLE2 "\n ------ begin $file ----- \n";
print FILEHANDLE2 @$file;
print FILEHANDLE2 "\n ------ end $file ----- \n";
}
Close fileto contrain contents of all files...
Just a quick example

Subject: References ch 8 programming Perl
Ok a couple questions on Ref from pg 251 programming Perl.
push @$arrrayref,$filename);
$$arrayref[0]="January";
@$arrayref[4..6]=qw/May June July/;
So this is actually creating an anonymous array that it then references correct? so
the assignments January ect are being made to an anonymous array.
This is cool but maybe I am missing the point. Why would you use these references
rather then just using the actual variable? If some one could give me some real world
applications for this I would be most appreciative.
I have seen them used to simulate a multidimensional array as well has hash and that
makes sense. But beyond that I am kind of at a loss.
