No, Sybase doesn't have sequences (AFAIK neither does MS-SQL).
Sybase has identity columns, and then you can write your own sequence
generators using stored procs, or whatever method you want to use.
There's a good write up on the various methods at
http://www.sybase.com/detail?id=860 (the document is 8 years old, but it's
still valid for the most part).
To get more information I would recommend the newsgroups at
news://forums.sybase.com (in particular the sybase.public.ase.* groups).
Lots of Sybase engineers and various other highly competent people read
these groups and help out.
The sybase-l mailing list hosted by ISUG (International Sybase User Group)
is good (go to www.isug.com to subscribe to the list).

Subject: OT: Sybase and Sequences (Was: Re: Retrieving Identity
Value of newly inserted row)
Holy cow, you mean Sybase doesn't have sequences?! I've just recently
started a financial job (which means sybase it seems) and my db
background is mostly PostgreSQL with some Oracle and a smattering of
MySQL.
Is it just me, or is Sybase ASE missing some pretty obvious RDBMS
features and conveniences?
I know that this list is Sybperl specific, but the people here seem
pretty reasonable :) Can anyone recommend a good list/forum/community
where Sybase things are discussed? Eg. in this case, I would be
interested to read a discussion about sequence best practises.
Cheers,
Mark.
