Abstract
Las anteriores y otras desventajas de la técnica anterior se superan de acuerdo con una realización preferida de este invento creando un aparato en un sistema de tratamiento de datos que descodificará un formato particular de instrucción, denominada, "retornar y enlazar", dará origen entonces a una transferencia de control a una instrucción en una dirección especificada por un registro de enlace, y alterará el contenido del registro de enlace para indicar la posición de memoria de la instrucción siguiente a la instrucción Retornar y Enlazar. Una vez que ha sido establecido el estado inicial del registro de enlace (por ejemplo, mediante una instrucción Bifurcar y Enlazar) el control puede ser transferido muy simplemente en las dos direcciones entre dos programas que funcionan concurrentemente mediante la utilización de instrucciones "retornar y enlazar". Este mecanismo hace posible así la comunicación entre programas de un modo muy eficiente en lo que se refiere tanto a tiempo como a posiciones de memoria. Facilita también enormemente la programación porque cada programa puede ser escrito sin consideración a la posición, tamaño, velocidad, etc. del otro programa. Cada programador simplemente distribuye instrucciones Retornar y Enlazar en lugares interrumpibles dentro de su programa sin restricciones que no sean algunos límites de preselección acerca de cuanto tiempo le puede ser permitido a un programa particular mantener el control del sistema antes de que transfiera el control en retorno al otro programa. Las anteriores y otras características y ventajas de este invento se pondrán de manifiesto por la siguiente descripción detallada de una realización preferida del invento, como se ilustra en el dibujo que se acompaña, que es un diagrama de bloques de una unidad de control microprogramada que realiza este invento.
