Sorry but i don't understand. After more attempts to permit to overwrite 
old file or create a new one and leave it readable:
...
my $prevumask = umask 0002;
open( GRAPH, "> $GRAPH" ); # file created has -rw-rw-r-- perms octal 0664
...
...
close( GRAPH );
umask = $prevumask; # reset file permission
------------------------------------------
But why setting umask to octal 0002 it create the file with octal 0664 
perms ?
