I've got something a bit screwy with my SQL Plus setup (at least thats what I think it is) For some reason I cant run scripts using the @ symbol:

i.e.
SQL> @crdb_minepw01_version9.sql
SP2-0734: unknown command beginning "crdb_minep..." - rest of line ignored.

Using Oralce 9.2.0.4 - Can anyone suggest anything?

Cheers,
Fraze
