Verfahren zum selektiven Erfassen und Auslesen einer Zeichenkette

摘要

Character strings inter alia are inputted into a data processing unit (1) during the normal course of operation. Said strings are outputted in a sequential character sequence via an output interface (4). The primary output signal flow thus produced is formatted in such a way that it can control an available printer (5). Position control signals added to the output signal flow cause the printer (5) to output a respectively allocated character string in a given output position. According to the invention, a converter (6) is coupled to the output interface (4) and placed in a configuration mode. The data processing device (1) is allocated a marking character string ("A06AAA") instead of each character string which is to be detected selectively. The output signal flow is received by the converter (6) and searched for marking character strings. When a marking character string is detected, identifying position information relating to the point of origin in the output signal flow is obtained from the position information signals which are also transmitted and stored along with the number of characters in the converter(6). In the subsequent operating mode, any number of character strings are detected in the marked positions of the output signal flow using stored position information, they are read and can be subsequently integrated with a secondary output signal flow in an appropriate manner. The format of the secondary output signal flow is modified according to an alternative output device (14). The signals constituting the secondary output signal flow are formed by data from an output memory (B) and by the character strings of the first output signal flow which are read from a memory (A) using a control device (8).
