1. A document processing system for processing information on documents read by a reader sorter includes a central processing unit, a main memory and a controller, all coupled in common to a system bus, said document processing system further including an adapter coupled to said reader sorter and said controller for processing said information, said document processing system comprising:

  • said adapter including,receiving means coupled to said reader sorter for receiving character signals representative of said information;

    random access memory means coupled to said receiving means and responsive to said character signals for selecting translated character signals, and said translated character signals having a selected one of said said translated character signals in a first state being representative of said character, and a control character, and having said selected one of said translated character signals in a second state being representative of said character being a queue filed identifier character for designating the boundary of a field;

    read only memory means coupled to said receiving means and responsive to said character signals for selecting a character identifier having a selected one of said character signals in a first state identifying said character, and having said selected one of said character signals in a second state identifying said control character as a pseudo queue field identifier character for designating the boundary of a field for transfer to main memory; and

    multiplexer means coupled to said random access memory and said read only memory means, and responsive to controller signals in a first state for selecting said translated character signals, and responsive to said controller signals in a second state for selecting said character identifier signals for transfer to said controller, wherein said controller is responsive to said translated character signals representative of said queue field identifier character and said character identifier signals representative of said pseudo queue field identifier character;

    said controller being further responsive to said translated character signals for generating a start position character count and an end position character count in a field for transfer to said main memory, said controller including,control means coupled to said adapter for generating said controller signals in said first state for selecting said translated character signals, and said controller signals in said second state for selecting said character identifier signals;

    arithmetic logic unit means coupled to said adapter, and responsive to said translated character signals, having said selected one of said translated character signals in said second state, for generating said queue field identifier character, and responsive to said character identification signals, having state, for generating said pseudo queue field identifier character; and

    scratch pad memory means coupled to said arithmetic logic unit means including first means for storing first signals representative of said queue field identifier character in a first address location representative of a field opening queue character, second means for storing said first signals in a second address location representative of a field closing character, third means for storing second signals representative of said pseudo queue field identifier character in said first address location, and fourth means for storing said second signals in said second address location of a scratch pad memory.
