Abstract: There is provided a method for executing a program comprising a function call and one or more subsequent instructions. The method comprises processing, on a first thread, a function defined by the function call, the function having one or more programmer predefined typical return values. For each predefined return value, the one or more subsequent instructions are pre-processed on an additional thread assuming that the function returned that pre-defined return value. In this way the processor, on completion of processing said function is able to make use of the pre-processing completed by the additional thread which used the actual return value.

Abstract: A method of highlighting linked-to document sections for increased readability uses standard <h1>, <h2> . . . <h6> tags or like to identify different sections within a page, and then highlights from the beginning of a newly-linked-to section up to the beginning of the next section that has an equivalent header tag or a header tag which is higher in the tag hierarchy.
