Abstract
Abstract A graphic display terminal (Fig. 1) is arranged to receive drawing instructions containing the description of a display character. The terminal, under control independent of the source, translates each received drawing instruction into a picture description bit pattern conforming to the characteristics of the terminal display device (7). The interpreted bits are then stored in a graphic repertory (10) for subsequent retrieval under control of code received from the source. In this manner dynamically redefinable character sets may be created and used without regard to a particular terminal implementation.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
76 words
An arrangement (FIG. 2) for delineating objects for display comprising means (1) for processing generalized drawing instructions received from a remote source, CHARACTERIZED IN THAT the processing means (1) comprises means (201) for translating the instructions into a pattern uniquely adapted for display, and means (10) for storing the unique pattern and for retrieving the stored pattern for display in response to commands from the remote source indicating only the storage location of the unique pattern.
Claim 2
Dependent Claim

Claim 3
Independent Claim
63 words
A method for delineating objects for display by processing generalized instructions received from a remote source, CHARACTERIZED IN THAT the method comprises the steps of translating the instructions into a pattern uniquely adapted for display, storing the unique pattern, and retrieving the stored pattern for display in response to commands from the remote source indicating only the storage location of the unique pattern.
