I have a 2 column table LU_ASMT_COMMUNITY with fields CODE and DESCRIPTION. If I run the following script I get these included results ..

select code || '*' || description || '*' || sysdate from lu_asmt_community

14O*Residual Ward 14 - Sub Area 14o*17-JUN-03
14P*Residual Ward 14 - Sub Area 14p*17-JUN-03
14Q*Residual Ward 14 - Sub Area 14q*17-JUN-03
14S*Residual Ward 14 - Sub Area 14s*17-JUN-03
14T*Residual Ward 14 - Sub Area 14t*17-JUN-03
UKN*TYPE UNKNOWN*17-JUN-03

But if I add a CHR(10) to the middle of the script, as follows, I get different results ...

select code || '*' || CHR(10) || description || '*' || sysdate from lu_asmt_community

14O*
Residual Ward 14 - Sub Area 14o*17-JUN-03

14P*
Residual Ward 14 - Sub Area 14p*17-JUN-03

14Q*
Residual Ward 14 - Sub Area 14q*17-JUN-03

14S*
Residual Ward 14 - Sub Area 14s*17-JUN-03

14T*
Residual Ward 14 - Sub Area 14t*17-JUN-03

UKN*
TYPE UNKNOWN*17-JUN-03

The data returned is correct but Sql*plus adds a blank line after each record returned. If I use Toad, another Oracle tool, I do not get this result. Does anyone know why this is possibly happening?

Common sense says that the character against that char(10) is a blank line i.e why that command behaves like that...

Nothing to worry abat!

Kyle,
chr(10) adds a new line.
Chr(10) and other formatting are meant to be used with sql*plus ( which is a TBI- text based interface ).
TOAD and other tools use a different font systems.
so, you may get different resullts or no results at all.
if you are still curious, try these
I have no toad with me.
I tried on sql*navigator, for
select ename||'*'||chr(10)||sal from emp;
the result displayed was 
ename*some_square_symbolsal
i copied the same text(form sql*navigator) and pasted here, in this html based forumn ( true and native fonts ) and u get the expected results

The problem was that there is a setting in SQL*Plus which, under certain circumstance, will add blank lines between the output records. To turn this off you have to set the follwoingproperty at the top of your script ...

set recsep off

This was not common sense problem. The other problem is that SQL*Plus will show a list of enviroment variables which can be set. Unfortunately this env. variable does not appear in the list.
