Hi,

I have 2 questions.

1) Avoid warning message

    use strict;
    use warnings;
    
    my $logfile = "test.log";
    my $log_fh = *LOG_FH;
    LOG_MSG_OPEN($log_fh,$logfile);
    
    ...
sub LOG_MSG_OPEN
{
    my $par_fh = $_[0];


    open($par_fh,"> $par_filepath") or die ("Can't open $par_filepath:
+ $!\n");
    $par_fh->autoflush(1);
}

[download]

gives me this error message: Name "main::LOG_FH" used only once: possible typo at...

Is the only way to get rid of the mssage to add 

#no warnings 'once';

?

2) Create FILEHANDLE name from a variable

my $logfile = "test.log";
my $log_fh = "LOG_FH";
LOG_MSG_OPEN($log_fh,$logfile);
...
sub LOG_MSG_OPEN
{
    my $par_fh = $_[0];
    my $par_filepath = $_[1];
    
    my $par_fh_2 = *${par_fh};
    
    open($par_fh_2,"> $par_filepath") or die ("Can't open $par_filepat
+h: $!\n");
    $par_fh_2->autoflush(1);
}

[download]

gives me this error message: Can't use string ("LOG_FH") as a symbol ref while "strict refs" in use..

Is it possible to create FILEHANDLEs with a variable

Thanks for help.

Regards, de Michi
