How to remove empty lines in multiple selects

Hi,

there is a script:

================

set heading off

prompt prompt1

select 'Text1' from  dual;

prompt prompt2

select 'Text2' from dual;

prompt prompt3

select 'Text3' from dual;

================

Output:

================

prompt1

Text1

prompt2

Text2

prompt3

Text3

================

Is there any way to force sqlplus not to put emply line after every select? I can't use external tools like perl/sed/awk to filter it out, I may only change sqlplus settings. I tried with

set heading off newpage none pagesize 0

but it doesn't help. I would appreciate your help with this.
