A method is described for dynamically defining virtual terminal characteristics on demand. A virtual terminal is a redefinition of a single display unit to enable multiple activities to be active under program control with only one physical resource committed. The Base Operating System (BOS) must know the characteristics of each virtual terminal. Such information as editor characteristics, environment and display characteristics and buffer size must be established for each virtual terminal. Most BOSs employ a command driven approach to define the virtual terminal characteristics. This approach involves a tedious fill-in- the-blanks approach to create a table of information. This table has to reside in memory for every virtual terminal employed.
