I must disagree. You can return a numeric value from 0 to 255 (?) from a sql*plus session. If you return a number larger than 255, it is the modulus of value/256.

$ echo $?

0
$ sqlplus "/ as sysdba"

SQL> exit 1

$ echo $?

1
$ sqlplus "/ as sysdba"

SQL> whenever sqlerror exit 1
SQL> select * from alskjfajafls;
select * from alskjfajafls

               *
ERROR at line 1:
ORA-00942: table or view does not exist

$ echo $?

1
$ sqlplus "/ as sysdba"

SQL> exit 254

$ echo $?

254
$ sqlplus "/ as sysdba"

SQL> exit 255

$ echo $?

255
$ sqlplus "/ as sysdba"

SQL> exit 256

$ echo $?

0
$ sqlplus "/ as sysdba"

SQL> exit 257

$ echo $?

1
$
