Replace all strings with vi

[Prog]

Is there a way in vi to replace all occurrences of a string with another string? Such as:

DEPAR with DEPARTMENT

??

[v0id]

This works in Vim, but I think it'll work in Vi too.

:%s/DEPAR/DEPARTMENT/g

v0id's suggestion works on vim as well as vi. Most Linux systems now use an alias for vi and actually execute vim when you type vi. After all, vim is only vi improved.
