    Abstract: The apparatus for entering information comprises a sequence of predetermined characters into an information processing system by means of a keyboard (12) having a number of keys, selected ones of which have a number of operating states. A device enters into the system code point, designation signals each representing a selected character in response to operating a corresponding key and code page designation signals each representing a keyboard operating state. The device for entering comprises a device (10,11,16,17) for entering only a code point designation signal when the associated character is in the same code page as the previous character in the sequence. Both a code page designation signal and a code point designation signal are entered when the code page of the previous character in the sequence is different.

    Abstract: A method of, and apparatus for, running several applications (50) concurrently on a processing system. Virtual terminals (30) are created for running the applications. However, the virtual terminals perform as though the processing system were a single terminal system. In this way, any application written for a single terminal system can run in this multiple virtual terminal environment. For interaction with one of the several applications running on this system, the real physical resources of the system are reallocated to the virtual terminal running the selected application.

    Abstract: Method of character generation for displaying or printing image data stored sequentially in a compressed font memory. The proper character is addressed during decompression by combining a calculated approximate pointer (25) obtained by multiplying the code of the character by an approximate pel dimension number, with a limited range correction factor (22, 26) stored with the font to obtain an exact start of character pointer utilized to address the image data for the character. Also stored with the correction factor is data (23) indicating the vertical positioning of the character within the character box (10).

    Abstract: An interactive display terminal of the multiple overlapping window type is provided. Each of the windows (42) is smaller in dimension than the overall display screen. One or more of the windows have an associated virtual distributed menu which is made up of a plurality of menu items (43-50) respectively distributed about the periphery (41) of the associated window but not displayed during normal operations. Cursor means and means for moving the cursor are also provided. The display terminal further includes apparatus which in response to the movement of the cursor across a selected region in a window periphery will effect the display of a selected menu item associated with the particular selected region. The overlapping windows are preferably rectangular in shape and the selected regions are adjacent to corners of the periphery. The menu items are distributed so as to be positioned adjacent to the respective region across which the cursor movement will result in the item display.
