One or more embodiments of the invention provide a method, apparatus, and article of manufacture for collaborating application programs executing on a client such as a personal digital assistant (PDA). A shared database on the client is obtained and used as a common launch parameter stack. One or more program entry records are stored in the database and the last program entry record stored is identified as the top of the stack. Each program entry record may include information regarding an application launched on the client. When the last program identified on the stack has completed execution, the last program entry record is popped off of the stack. Thereafter, control is returned to an application that corresponds to the new program entry record on the top of the stack.
