Of course this example is what happens in SQL*PLUS.
But it looks like TOAD is not quite emulating SQL_PLUS (at least when it comes to SERVEROUTPUT settings).
I've tested whether an EOL sequence is transmitted for NULL / empty lines (using DBMS_OUTPUT.GET_LINE to retrieve the lines), and it definitely is sent for every occurrence of DBMS_OUTPUT.PUT_LINE and DBMS_OUTPUT.NEW_LINE - so I can only assume that TOAD is throwing away a line that consists of just an EOL sequence.
SERVEROUTPUT in TOAD also does not respect whatever LINESIZE has been set either (at least in the Script Output tab).
All of this is assumed to have been executed using F5. If you use "Execute SQL via SQL*Plus", it works as expected.

By default, if you just execute SET SERVEROUTPUT ON, it defaults to FORMAT WORD_WRAPPED. That setting suppresses all blank lines.
Issue SET SERVEROUTPUT ON FORMAT TRUNCATE or SET SERVEROUTPUT ON FORMAT WRAPPED and you will get what you want:
** SQL> set serveroutput on
SQL> create or replace procedure dbmsoutput_test as 2 begin 3 dbms_output.put_line('a'); 4 dbms_output.put_line(null); 5 dbms_output.put_line('b'); 6 end;7 /**

Null is not a character. There is nothing to display when you write that to output.Try this in SQL*Plus and you'll see the same. create or replace procedure dbmsoutput_test as begin dbms_output.put_line('a'); dbms_output.put_line(null); dbms_output.put_line('b'); end; / exec dbmsoutput_test; On 02/12/2014 01:28 AM, sdstuber wrote:

I know I can stick "invisible" dummy values but what I'm looking for is output that reflects what my code actually did.
If I run the block above it seems reasonable that I would get 2 lines consisting of nothing but the end-of-line delimiter but I don't.
Let's make it a little more real. Let's say I'm looping through a cursor of a single column and outputing the values. Some rows have null.
If my cursor iterates through 15 rows with 4 nulls I'll only get 11 rows of output even though the code called put_line 15 times.
