Abstract: Software, methods and devices for executing textually-defined instructions at a wireless communication device are disclosed. The instructions may be for performing a mathematical operation upon specified integer or floating-point operands, for performing one or more specified actions for each pass through a loop, for performing one of two sets of actions based on a user selection of one of two user interface controls, or for triggering a timer for delaying a subsequent action by a specified time interval. The instructions may be defined in a markup language such as Extensible Markup Language (XML). The software, methods and devices may form part of a system for allowing varied wireless communication devices to interact with server-side software applications.

Abstract: A markup language document (e.g. an XML document) may contain a first instance of a markup language element having an attribute with a first, platform-independent value, a second instance of the element having the attribute with a second, platform-specific value, and an indicator that the second value overrides the first. Executable code may replace both of the first and second instances with a single instance having the attribute with the second value. Alternatively the markup language document may contain a first instance of a markup language element having a first, platform-independent attribute, a second instance of the element having a second, platform-specific attribute different from the first attribute, and an indicator that the second instance extends the first. In this case executable code may replace both instances of the markup language element with a single instance having the first attribute and the second attribute.

Abstract: To enable use of an application on an application server at a mobile communication device, at a transaction server, a message received from the mobile is pushed out to the application. Any return messages is routed back to the mobile. The transaction server may use a queue to store all messages destined to a given application and attempt to push all messages on a given queue on receipt of a further message for the queue.
