alter table alter column to resize a varchar

Hi folks.

I'm planning on extending a field in one of my main tables using:

alter table stock alter column type varchar(255);

to extend it from the current varchar(80).  My concern is that this table and
this field is used in a number of views, and views of views.

Are then any gotchas that I need to worry about or things I need to check, or
will it just work?
