Sybase 5.55 running over QNX 4.25

Hy. I have to do some modifications over a sybase 5.55 data base which is running over QNX 4.25 OS and i would need a manual, tutorial or a web page which explains the way to create an modify tables, recover the date base when the log is corrupt…
Thank´s.

Sybase 5.5.05 may be?
use dbsrv50,
run isql, F1 after that!
