Hi please can any one explain me what does the following code does , what is the use of USAGEMSG or USAGE 
use constant USAGEMSG => <<USAGE;
Usage:ftp.pl  [options] host:/path/to/directory

Having a 'Seekers of Perl Wisdom' IMHO is not an excuse for not trying to search for obvious info by oneself. In particular since you see use constant you should really check perldoc constant. Then you would find out that 'USAGEMSG' is a constant (a sub, really, you may have done 
sub USAGEMSG () { ... }

instead).

'USAGE' is "nothing but" a "tag", but this is basic perl syntax. Please check perldoc perlop and look for "here-document".
