A zoom control mechanism includes a context display for displaying a representation of a data set, a zoom display for displaying a representation of a zoom interval within the data set, a context indicator that indicates a start point or an end point of a zoom interval within a context display, and a zoom indicator, corresponding to the context indicator, that indicates the start point or end point of the zoom interval within the zoom display. The zoom interval is updated according to user selection and movement of the context indicator and the zoom indicator to a new location within the context display and the zoom display, respectively.

A method and apparatus are disclosed for monitoring software applications within a first processor during development thereof. A limited number of uniquely identifiable elements or 'hooks' are inserted into the software application under development and each time an element is encountered during processing of that software application, the identity of the element and a selected data frame are coupled to the output bus of the first processor. A data output card is utilized to couple that information to a data collection card via a dedicated cable. The data collection card is then utilized to transfer the identity of each element encountered and its associated data frame along with a time value, to a second processor, which is utilized to record that data. In one embodiment of the present invention, a switched bank memory system is utilized in the second processor to permit high speed data storage. In the event the software application under development generates monitoring outputs at a speed greater than may be accurately stored within the second processor, an overrun indication is stored within the second processor and subsequent tests may be run utilizing fewer 'hooks' within the software application under development.
