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 graphical system resource monitor is provided to depict, in real-time, a data processing system's internal resource utilization. A window or viewport of a data processing system displays user specified internal system resources, such as memory, CPU, or peripheral device availability/utilization. This graphical representation of the `state` of the data processing system's resources is maintained in real-time, while the impact on the system's performance in providing such information is kept to a minimum. This is accomplished through a combination of various techniques, including specialized device drivers for the respective devices coupled with a unique data reduction technique. The graphical results of these resource monitors are continually updated in real-time. This real-time support provides an immediate and accurate representation of the internal operations of the data processing system. Further, these resources can be monitored at the process level of a multiprocessing system. These representations can be used by a user to identify, isolate, and fine-tune the data processing system's resources to improve the overall efficiency of the system being monitored.

A system and apparatus is described to check pages in memory that are allocated to all processes and the operating system, and to check the pages in memory that are allocated to each individual process, in order to determine total RAM usage and RAM usage for a particular process, respectively. In order to determine total RAM usage for all processes and the operating system, a page frame table is used to count all memory pages being used. System memory pages, all process pages and unassigned pages are marked in a page frame table using a specific marking process. These marked pages are then summed and categorized for their particular usage, i.e. free memory, system memory or process memory. The RAM memory usage for a particular process can also be determined. First, RAM usage from operating system control blocks assigned to the specific process is computed. Next, the private memory area and shared memory area used by the process is determined by finding the pages associated with a memory object and counting the actual pages being used. The counted pages are then added to determine the total RAM in use for the particular process.

A method and apparatus for transforming data transmitted from a remote information processing system which operates in a first internal code format to the internal code format of a second receiving information processing system. The method includes a control program for operating the receiving information processing system in an interactive mode with the operator. The control program displays prompts and command options to the operator which enables the operator to construct a transform table of conversion characters for the communication session. The conversion table is also useable by the control program routines to reverse the data transmission operation by converting the internal code format of the second information processing system to the internal code format of the first information processing system for data transmission in the opposite direction.
