A system for merging data flow having a typewriter electronically connected to a buffer, which is a dynamic electronic shift register, for inputting data into sections of the buffer and for merging the data in the sections into a single printout. System control logic is provided to allow (1) a separator, or partition, code to be input into the buffer for defining sections (2) codes corresponding to hold and operation flags to be input into the sections, and (3) text data codes corresponding to characters and switching and/or stopping points to be input into the sections. In addition, the system control logic is operable to allow the operator to insert characters into and delete characters from the sections of the buffer for text editing and revision. The sectioned buffer formed by the input of a separator code, or flag, can also be in electronic association with a record reader, or reader-recorder, such that the operator, by depressing a section store button and operating an alternate section button, can store the contents of records such as cards, tapes, etc., into the desired section of the buffer. With the codes and characters stored in the buffer, the section containing the first text to be printed is addressed, printout is initiated from the operation flag and continues until a switch code is encountered. Then the positions of the hold and operation flags contained in the two different sections are automatically exchanged and printout continues in the other section from the operation flag with the result being the merging of text stored in the sections.
