How to change the default directory from within SQL*Plus ?

Question

Hello,
I want to change the default directory directly from within SQL*Plus to be able to launch my command files with simple instructions like :
@my_command.sql
If I haven't launched SQL*Plus from the directory containing the file my_command.sql, how do I change the default directory to the directory of my command files ?
I've searched through the Oracle documentation, there's no SET DEFAULTDIR or something like that. When I do a SHOW ALL, there's no variable containing the default directory.
If you have an idea...
regards,
Jérôme.

Hi Jérôme (J鲴me ?),
You cannot directly do that, but you can use @@ instead of @ to run subscripts in the same directory as the superscript
# head /tmp/tl30/xxx/[xyz].sql                    
==> /tmp/tl30/xxx/x.sql <==
prompt call y
@y
prompt call z
@@z
quit
==> /tmp/tl30/xxx/y.sql <==
prompt i am in y
==> /tmp/tl30/xxx/z.sql <==
prompt i am in z
# pwd                                             
/root
# sqlplus -s scott/tiger@lsc62 @/tmp/tl30/xxx/x.sql
call y
SP2-0310: Datei "y.sql" konnte nicht geöffnet werden
call z
i am in zKind regards
