LongReadLen not working with Pervasive

Hello,

I would appreciate your help with the following question.

I'm using DBD::ODBC to connect to a pervasive database. There is a column 
in the table that is defined as LONGVARCHAR - 31999 bytes.

The fetch statement on the column fails with the following error

[Pervasive][ODBC Client Interface][LNA][Pervasive][ODBC Engine 
Interface]Data truncated column 1. (SQL-01004)
[Pervasive][ODBC Client Interface]Data truncated column 1. (SQL-01004) 

I set LongReadLen to 31999 and LongTruncOk to False to resolve the issue. 
I don't get an error now, but the data is getting truncated to 80 
characters.
Is there an issue with the Pervasive ODBC driver not supporting 
LongReadLen?

my $sql_col1;
        $dbh->{LongReadLen} = 31999;
        $dbh->{LongTruncOk} = False;
        print $dbh->{LongReadLen};
 
        if ( !$sth->bind_columns( undef, \$sql_col1 ) ) { 
        print $LOG_FH
"Error encountered when binding columns in SQL statement $sql_to_run - 
$DBI::errstr\n";
            $rc = 1;
            return ( $rc, \@db_records );
        }

        my $reccount = 0;
        while ( $sth->fetch ) {
            #Remove trailing spaces
            $sql_col1 =~ s/\s+$//;
            $db_records[$reccount] = $sql_col1;
            $reccount++;
        }

Thanks,
Saraswathi
