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…

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