Unsetting autoextend?

Hey;

I'm having difficulty decyphering the Oracle documentation; I'm trying to turn off the auotextend feature on a tablespace. I keep getting "missing or invalid alter tablespace option".

What I've tried is as follows:

alter tablespace ${ts}
autoextend off;

alter tablespace ${ts}
set autoextend off;

alter tablespace ${ts}
storage (autoexend off);

alter tablespace ${ts}
default storage (autoextend off);

Can someone fill me in on the correct syntax?

Thanks!

Doug
