How do I conditionally create a table in Sybase (TSQL)?

OK, so Sybase (12.5.4) will let me do the following to DROP a table if it already exists:

IF EXISTS (
    SELECT 1
    FROM sysobjects
    WHERE name = \'a_t

    The only workaround I've come up with so far is to use execute immediate:

    IF NOT EXISTS (
        SELECT 1
        FROM sysobjects
        WHERE name = 'a_table'
        AND type = 'U'
    )
    EXECUTE("CREATE TABLE a_table (
        col1 int not null,
        col2 int null
    )")
    GO
    

    works like a charm, feels like a dirty hack.
