Dear Monks,
I am running into this weird problem with variable scoping.
Below is my sub-routine, populatemessagedefs. I am passing hash reference and a string to the sub-routine.
Scope of the sub-routine is to populate hash by splitting the string ($Everythingelse) by ',' and inserting it in the hash.
Example <\br> $Everythingelse holds (Tom,18,Jack,22,Tim,30)
The sub-routine iterates in the foreach loop and inserts following in hash
Result Set:
Key->Tom Value->18
Key->Jack Value->22
Key->Tim Value->30
The problem is after every ‘foreach’ iteration '$i' resets to 0, even if I increment value of $i.
Am I missing something completely obvious?
sub populatemessagedefs()
{
    my ($ref_to_msg_defs,$Everythingelse) = @_;            
    my $temp_value;
    my $temp_key;
    my @Interface_Message_List = split (',',$Everythingelse);
    my $i=0;
    
    foreach my $field(@Interface_Message_List) {
        #In next iteration $i is ‘0’ again
        if ($i == 0) {
            $temp_key =  $field;
            $i++;    
            #Value of $i is 1 now        
        }    
        elsif ($i == 1) {
         
            $temp_value = $field;
            
            if (exists $ref_to_msg_defs->{$temp_key}) {
                if ($field > $ref_to_msg_defs->{$temp_key}) {
                    $ref_to_msg_defs{$temp_key} = $field;
                    $i--;
                }    
            }
            else {
                $ref_to_msg_defs{$temp_key} = $field;
                $i--;                
            }            
        }    
    }    
}
