I know someone has already answered this, but you can find the official answer in the documentation. Look up the description of v$lock in the Server Reference Manual. From the 9.2 manual (Oracle9i Database Reference Release 2 (9.2) Part Number A96536-02), description of column v$lock.lmode:

LMODE NUMBER Lock mode in which the session holds the lock:

0 - none 
1 - null (NULL) 
2 - row-S (SS) 
3 - row-X (SX) 
4 - share (S) 
5 - S/Row-X (SSX) 
6 - exclusive (X)
