TAM is a prototype computational aid for non-programmers, particularly engineers or scientists, that uses ordinary two-dimensional mathematical notation as its language. The system includes an arithmetic interpreter, incorporating an extensive set of arithmetic operators on constants, variables, and arrays, that accepts hand-printed graphic (two-dimensional) input from a data tablet and supplies two-dimensional output via a projection display system. TAM is one of a class of potential interactive graphics systems useing natural language to improve man-machine communication.

    Another quite elaborate pen language, Tam, has
    been recently developed at System Development Corporation
    [Saylor, 1972]. The motivation for this
    work, as it is for nearly all such systems, is to
    provide more natural scientist-computer interaction.
    Most of the common two-dimensional mathematical
    constructions of expressions appear in this language
    including a superscript form for matrix transpose.
    A few special notational conventions are
    employed due to the ambiguities that occur in handwritten
    English as used in the United States (e.g.
    there is insufficient difference between a one,
    "]", and a vertical bar, "I"). Whereas the
    Blackwell-Anderson system combines both keyboard
    and pen control facilities, in this system, all input
    interaction involves a stylus.
