Such a language-specific realization, in which the language-independent system nucleus is embedded, is called a language layer. Language layers for FORTRAN and Pascal are available (see examples

In order to meet these requirements while maintaining device independence, three coordinate systems have been defined in GKS. The application programmer uses the world coord

The effects of functions are partly defined as the change of values in state lists that is caused by their invocation. The operating state has one of the following five values:
