Hi, Here is my code snippet 
#!/usr/bin/perl 
 
my $logFile = $ARGV[0];  
die "usage: $0 <logFile>" unless $logFile;  
die "Logfile $logFile doesn't exist" unless -f "$logFile";  
open($log, "<", $logFile) or die "Can't open $logFile for reading.";  
print "Processing file $logFile...\n";  
my $n = 0; 
my $ArcotIDError_Count = 0; 
my $QnAError_Count = 0; 
my $UPError_Count = 0; 
my $OTPError_Count = 0; 
my $errorCode; 
while( $line = <$log> )  
{  
       $n++;  
    $line =~ tr/\r\n//d; 
    if ($line =~ /recvd AA_BIN_MSG_VER_CHG/)  
    { 
        while( $line = <$log> ) 
        { 
            if($line =~ /Handling NSPAdvice for mechanism \[4\]/)  
            { 
                while ( $line = <$log> )  
                    { 
                        if ($line =~ /Authentication mechanism returne
+d \[(\d+)\]/)  
                        { 
                            my $errorCode = $1; 
                            print "$errorCode\n"; 
                            if ($errorCode != 0 && $errorCode != 1)  
                            { 
                            $ArcotIDError_Count++; 
                            } 
                        } 
                    } 
            } 
        }     
     } 
} 
    print "Total Number Of ArcotID Authentication ErrorCode returned i
+s $ArcotIDError_Count\n";

This code does not give me correct output. Correct output according to my logfile is 142 but it gives me 352. I want to count it in between these lines 
    
starting point-
Apricot Native Server: recvd AA_BIN_MSG_VER_CHG
and
ending point-
(Prepared to Send OK) OR (Sending Invalid credential).

I can check the begining statement here but for end statement(so that i always get the out between those lines) what change needed in the code. Thanks NT
