Is there a 'LIST' function in SYBASE that would take query about and present it as one string?

Example: select name_column from test_table

Output if using special function: name1, name2, etc.
instead of name1
name2
name3

If SYBASE does have this function, I was wondering if SQLServer 6.5 had one similar....I cannot find it in any of the books.

Thanks for any help!
