Just a hunch (my hunch was wrong, see Update below), but try removing the single quotes from the filehandles in your open() and close() statements.

Change this: 

open( 'USERS' , 'file' );

To this: 
open( USERS , 'file' );

[download]
and while we're at it, let's check the results of the open: 
open(USERS, 'file') or die "unable to open `file': $!";

[download]

Update: my hat's off to tye on the use of a string literal for a filehandle. How many times have I glossed over the following in perlfunc and not noticed? 

If FILEHANDLE is an expression, its value is
used as the name of the real filehandle wanted.

I suppose what threw me is that I've seen no examples of literal strings used to specify filehandles. Live and learn.
