On the semantics of the assignment statement of high-level graphical languages
Based on the concept of treating graphical data as a data type in its own right with associated language parts and constructs such as graphical constants, graphical variables and graphical expressions, the semantics of the assignment statement of a high-level graphical programming language are investigated in some detail.It is assumed that the graphical data are defined by the areal external representation model. In addition, the semantics of binary operators, the superposition and the deletion operators, are considered.
