  • (a) a first processing environment, including a first application;

    (b) a second processing environment including a second application;

    (c) terminal emulation means for storing a virtual screen;

    (d) communication means for coupling said terminal emulation means to said second application, to allow said second application to write prompts to said virtual screen, to read data from said virtual screen, and to write data into said virtual screen; and

    (e) conversion means, interconnecting said first application with said terminal emulation means, for receiving service requests from said first application and converting each of said service requests into a dialog wherein the conversion means waits for the second application to write a series of prompts into said virtual screen and, in response to each of said prompts, writes data derived from said service request into said virtual screen, and wherein the conversion means constructs response messages containing data derived from said virtual screen and returns said response messages to said first application.
