Opening and closing files in loop	Can't Post

Hey, I've got some problems with a little program. I want to write into 2 files but the ouput-structure differs inside those two.

I use this code:

Code

    for ($i=1;$i<=$max;$i++){  
       
        $pwd = &randomPwd($nmbchars); 
        select (DB); 
        print qq("$dept$w$i","7 days","$pwd",,,,,,\n); 
        close(DB); 
        select (newDB); 
        print qq("$dept$w$i"\t>\t"$pwd"\n); 
        close(newDB); 
 
    }

The loop just runs 1 time and then the program stops. It should run multiple times.

Is there a restriction in opening and closing files inside a loop?

what is the value of $max
i am only a beginner but i think the sintax for the loop is this

for (my $i=1; $i<$max; $i++)

try this

Code

    for (my $i=0; $i < $max; $i++){   
        
        $pwd = &randomPwd($nmbchars);  
        select (DB);  
        print qq("$dept$w$i","7 days","$pwd",,,,,,\n);  
        close(DB);  
        select (newDB);  
        print qq("$dept$w$i"\t>\t"$pwd"\n);  
        close(newDB);  
  
    }

I don't think this will work any better.

@IT007: why don't you simply use file handlers to write to your files?
