Spatial Grasp Language (SGL)

The chapter offers Spatial Grasp Language details which may be particularly useful for better understanding of many practical examples in the subsequent chapters. It first briefs the Spatial Grasp Model and Technology where SGL is its basic language, providing summary of its syntax and main constructs. Then describes different types of SGL constants and variables with their features, spatial distribution and possible movement, also full repertoire of SGL rules with their semantics and practical use, which include type, usage, movement, creation, echoing, verification, assignment, advancement, branching, transference, exchange, timing, qualification, and grasping. Elementary examples of programming in SGL are provided, also references to existing SGL publications and its previous versions called WAVE.
