    structures  called Displaygroups. A class of set operators (FOR A { DO…) allows the user to selectively traverse a data structure. As part of the definitional language a computational facility is available which allows the definition of structures algorithmically.
    DPL operates in two modes. The first, an interactive mode, allows the user to define, display, and modify structures from a Teletype console. The second mode, known as a stored program, allows the user to define a sequence of DPL commands and then execute them as a program. Decision and recursive call statements are available when operating in the stored program mode.
